That time in the scientific field is called \u201ctime scale\u201d. This talk will discuss how the Colombian time scale was developed, how it is generated, and what it is used for in Colombia. Legal Time is important for the academic, scientific, and industrial groups, as well as the citizens. Each group needs different levels of accuracy depending on the intended use of their event dating activities. Therefore, the achievements in establishing the Calibration and Measurement Capabilities (CMC) for the magnitude of time and frequency in Colombia over the last 13 years are presented and how these achievements are reflected in the dissemination of metrology in Colombia, being the first CMC published in the Key Comparison Database (KCDB) of the BIPM (for its French acronym, Bureau International des Poids et Mesures) in the country&#8217;s history. The talk will show that international cooperation has been a key tool for the current development of the Time and Frequency Laboratory of the National Metrology Institute of Colombia (INM) and to expand the dissemination of metrological traceability to the International System (SI) of units in the country together with proposals of further work.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div data-dce-advanced-background-color=\"#FEC629\" class=\"elementor-element elementor-element-28d1d6f elementor-widget elementor-widget-heading\" data-id=\"28d1d6f\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h5 class=\"elementor-heading-title elementor-size-default\">Talk #2<\/h5>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e0e9045 elementor-widget elementor-widget-heading\" data-id=\"e0e9045\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Optical Clocks with Trapped Ions<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1247990 elementor-widget elementor-widget-text-editor\" data-id=\"1247990\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>\u201cNever measure anything but frequency\u201d was the motto of Arthur Schawallow. Through the measurement of frequency, we can measure any other quantity and inherit, in the process, the same exactitude. By the careful determination of the perturbation of the frequency of a given oscillator, we can fully characterize its environment: the electric and magnetic fields or the mass of the particles that surround it and even observe relativistic effects. Our understanding of nature seems to be limited by our capacity to measure frequency. What are the key ingredients to building the optimal oscillator? How can we reach and break the limits of precision and accuracy?<\/p><p>This brief talk introduces the development of optical clocks as possible answers to these questions. Optical clocks are based on the precise and accurate interrogation of atomic transitions. These kinds of clocks work in the optical regime of the electromagnetic spectrum, meaning that they operate at transitions that oscillate at more than 400 THz with bandwidths on the sub-Hertz level, allowing us to reach accuracies up to one part in 1018 or even lower. During this talk, I will introduce the necessary elements for the development of optical clocks with trapped calcium and aluminum ions.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-section elementor-top-section elementor-element elementor-element-036339c elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"036339c\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-8a70695\" data-id=\"8a70695\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-cbfd8e8 dce_masking-none elementor-widget elementor-widget-image\" data-id=\"cbfd8e8\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"239\" height=\"300\" src=\"https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/11\/headshot-239x300.jpg\" class=\"attachment-medium size-medium wp-image-3502\" alt=\"headshot\" loading=\"lazy\" srcset=\"https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/11\/headshot-239x300.jpg 239w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/11\/headshot.jpg 422w\" sizes=\"(max-width: 239px) 100vw, 239px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f1fdbf6 elementor-widget elementor-widget-heading\" data-id=\"f1fdbf6\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-medium\">Marina Gertsvolf<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-f4974f9\" data-id=\"f4974f9\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div data-dce-advanced-background-color=\"#FEC629\" class=\"elementor-element elementor-element-f5831de elementor-widget elementor-widget-heading\" data-id=\"f5831de\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h5 class=\"elementor-heading-title elementor-size-default\">Moderator<\/h5>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7625f55 elementor-widget elementor-widget-text-editor\" data-id=\"7625f55\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Dr. Marina Gertsvolf is the Team Leader for Frequency and Time (F&amp;T) group at NRC and is responsible for realizing the second, an SI unit of time, and for maintaining and disseminating the official time for Canada, UTC(NRC).\u00a0<br \/><br \/>Dr. Gertsvolf received her Ph.D. from the University of Ottawa in 2009 and joined NRC as a research officer the same year.

As a low-cost and portable imaging modality, ultrasound will play a key role in correcting these disparities. However, access to ultrasound technology is limited by the availability of trained sonographers and readers in rural areas. As a solution, an ultrasound-based telemedicine imaging system has been developed for deployment in rural areas in which ultrasound na\u00efve rural health workers perform volume sweep imaging (VSI) protocols based on only external body landmarks for diagnosing obstetrical, gallbladder, and thyroid pathology. Our telemedicine ultrasound system was piloted in an academic setting at the Pontifical Catholic University of Lima (PUCP) and in the Peruvian rainforest. Health workers were trained on VSI protocols, image capture, labeling, and electronic transmission over 2-3 days. Trainees then obtained images from patients requiring obstetrics, gallbladder, or thyroid scans. Images were uploaded to a cloud-based system and then downloaded and read by radiologists all using custom software. Preliminary results suggest that trainees can learn VSI protocols within 3 days. Our complete telemedicine system can provide a low-cost and scalable diagnostic service suitable for deployment in rural areas.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-section elementor-top-section elementor-element elementor-element-b69f028 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"b69f028\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-55870c3\" data-id=\"55870c3\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-0e8c8dd dce_masking-none elementor-widget elementor-widget-image\" data-id=\"0e8c8dd\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"300\" height=\"300\" src=\"https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/09\/costa-300x300.jpg\" class=\"attachment-medium size-medium wp-image-3410\" alt=\"costa\" loading=\"lazy\" srcset=\"https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/09\/costa-300x300.jpg 300w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/09\/costa-150x150.jpg 150w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/09\/costa-768x768.jpg 768w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/09\/costa.jpg 780w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9e41b78 elementor-widget elementor-widget-heading\" data-id=\"9e41b78\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-medium\">Eduardo Tavares Costa<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7cfbe9d elementor-align-center elementor-widget elementor-widget-dyncontel-popup\" data-id=\"7cfbe9d\" data-element_type=\"widget\" data-settings=\"{&quot;trigger&quot;:&quot;button&quot;,&quot;open_animation&quot;:&quot;enterFromTop&quot;,&quot;open_timingFunction&quot;:&quot;ease-in-out&quot;,&quot;open_delay&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:0,&quot;sizes&quot;:[]},&quot;close_animation&quot;:&quot;exitToBottom&quot;,&quot;close_timingFunction&quot;:&quot;ease-in-out&quot;}\" data-widget_type=\"dyncontel-popup.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t<div class=\"dce-button-wrapper\">\n\t\t\t\t\t\t\t\t\t<button class=\"dce-button-open-modal dce-button-popoup dce-animation-\"\n\t\t\t\t\t\t   data-target=\"dce-popup-7cfbe9d-4\"\t\t\t\t\t\t\t>\n\t\t\t\t\t\t\t\t\t\t\t<span class=\"dce-button-text\">Author Bio<\/span>\n\t\t\t\t\t\t\t\t\t\t<\/button>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"dce-popup-container dce-popup-container-7cfbe9d dce-popup-button\">\n\n\t\t\t\t\t\t\t\t\t<div id=\"dce-popup-7cfbe9d-4-background\" class=\"animated dce-modal-background-layer modal-background-layer\" data-dismiss=\"modal\" data-target=\"dce-popup-7cfbe9d-4\"><\/div>\n\t\t\t\n\t\t\t\t<div id=\"dce-popup-7cfbe9d-4\"\n\t\t\t\t\t class=\"dce-popup-7cfbe9d dce-modal modal-hide-esc modal-center modal-middle \"\n\t\t\t\t\t tabindex=\"-1\"\n\t\t\t\t\t role=\"dialog\"\n\t\t\t\t\t >\n\n\t\t\t\t\t<div class=\"modal-dialog animated\" role=\"document\" >\n\t\t\t\t\t\t<div class=\"modal-content\">\n\n\t\t\t\t\t\t\t<div class=\"modal-body\">\n\t\t\t\t\t\t\t\t<p>Eduardo T.

The development of the platform was funded by FINEP\/MCTI and FNS\/MS, Brazilian agencies linked to the Ministry of Science, Technology, and Innovation (MCTI) and the Ministry of Health (MS). The academic team was composed of 15 researchers and MSc and Ph.D. students and the technical institute involved more than 26 hardware and software engineers. By the end of this project, two versions of this ultrasound research platform were developed. In this presentation, we will show the main characteristics of the second and more flexible platform version. It consists of a 64-channel FPGA-based hardware with two 32-channel transmitters (TX) and receiver (RX) boards, a control board, multiplex, and backplane boards. It is possible to use a 128-element matrix transducer using the mux board. The hardware provides all RF data processed in a GPU board inside a personal computer equipped with two 3.0 USB interfaces (each interface is connected to a 32-channel RX board). The user interface allows the researcher to define and produce traditional (B-mode, Doppler, and M-mode) images and, also, create different imaging techniques. It is possible to acquire up to 128 individual RF A-line.<\/p><p>In the RX board is actually implemented the traditional delay-and-sum method before data are sent to be processed in the PC GPU board. Each RBTU research group is now using the platform to conduct their own research. In our group, we are using the platform to implement the fast plane-wave imaging technique and also to characterize ultrasound transducers. All new applications will be made available to RBTU members. <\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-section elementor-top-section elementor-element elementor-element-d9a2050 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"d9a2050\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-78db461\" data-id=\"78db461\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-e096ea8 dce_masking-none elementor-widget elementor-widget-image\" data-id=\"e096ea8\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"300\" height=\"300\" src=\"https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/09\/jean-300x300.jpg\" class=\"attachment-medium size-medium wp-image-3412\" alt=\"jean\" loading=\"lazy\" srcset=\"https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/09\/jean-300x300.jpg 300w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/09\/jean-150x150.jpg 150w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/09\/jean-768x768.jpg 768w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/09\/jean-1024x1024.jpg 1024w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/09\/jean.jpg 1200w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-69eb4fe elementor-widget elementor-widget-heading\" data-id=\"69eb4fe\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-medium\">Jean-luc Gennisson<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-38a62f6\" data-id=\"38a62f6\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div data-dce-advanced-background-color=\"#FEC629\" class=\"elementor-element elementor-element-5be4261 elementor-widget elementor-widget-heading\" data-id=\"5be4261\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h5 class=\"elementor-heading-title elementor-size-default\">Moderator<\/h5>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0fd76cd elementor-widget elementor-widget-text-editor\" data-id=\"0fd76cd\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Joining the CNRS (the French National Center for Science) in 2005 as a permanent researcher, Gennisson has mainly developed the ultrafast ultrasound imaging technique and especially the elastography technique to quantify the stiffness of biological tissue. Gennisson drove more than 15 clinical protocols on elastography development. This work took the continuation of his Ph.D. which concerned a 1D ultrasound imaging device, the &#8220;Fibroscan\u00ae&#8221; which is now commercialized by the company Echosens\u00ae and use for the clinical diagnosis of liver fibrosis. During these years of development, he has contributed to improving the elastography technique by creating new 2D and 3D modes, allowing the quantification of other mechanical parameters of tissues such as viscosity, anisotropy, elastic nonlinearity. In 2014, he has conceptualized and built the first 4D ultrafast ultrasound platform to provide volume information\u2019s in elastography but with no real-time approach. In 2017, Gennisson moved to IR4M laboratory that became BIOMAPS laboratory in 2020, to become head of the team \u201cMethodological developments and instrumentation\u201d (25 people with permanent position).<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-section elementor-top-section elementor-element elementor-element-7bd1146 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"7bd1146\" data-element_type=\"section\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-4b8646a\" data-id=\"4b8646a\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-0689c06 elementor-widget elementor-widget-heading\" data-id=\"0689c06\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Webinar #3: 30 August, 2021 at 2:00pm EDT (UTC -4:00)<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-67d3405 elementor-widget elementor-widget-heading\" data-id=\"67d3405\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h4 class=\"elementor-heading-title elementor-size-medium\"><b>Featured Topic: Acoustic Vortex Beams -

Current research interests at LaVA are aimed to: a) exploring different transducers technologies to be used in air-coupled ultrasonic applications, such as acoustic imaging, non-destructive testing, robot navigation, particle manipulation, etc.; b) material characterization through non-contact ultrasonic techniques, this includes laser-based ultrasound and ultrasonic spectroscopy; c) modeling, fabrication and characterization of electromechanical-acoustic sources;d) Vibration and acoustics in industrial environments; d) vibroacoustic characterization of Colombian autochthonous musical instruments and e) acoustic vortex beams.<\/p>\t\t\t\t\t\t\t<\/div>\n\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<button type=\"button\" class=\"dce-close dce-modal-close close-x close-right close-top\" data-dismiss=\"modal\" aria-label=\"Close\">\n\n\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"dce-quit-ics\"><\/span>\n\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t<\/button>\n\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-33b7265\" data-id=\"33b7265\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div data-dce-advanced-background-color=\"#FEC629\" class=\"elementor-element elementor-element-61d5aa7 elementor-widget elementor-widget-heading\" data-id=\"61d5aa7\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h5 class=\"elementor-heading-title elementor-size-default\">Main Talk<\/h5>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-df3e3d1 elementor-widget elementor-widget-heading\" data-id=\"df3e3d1\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Electroactive Diffraction Gratings: An Efficient Alternative for High-Quality Airborne Ultrasound Vortex Beam Generation<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-fad0768 elementor-widget elementor-widget-text-editor\" data-id=\"fad0768\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Acoustic vortex beams (AVB) have shown great potential in different emerging applications, such as contactless particle manipulation, transfer of angular momentum to matter, acoustic imaging, communications, and more recently, in biomedical applications. Different methods for AVB generation have been proposed, e.g., physically spiral sources, phase-driven sources, passive metastructured devices and electroactive spiral gratings.\u00a0 Notably, most of them have been developed in water, whereas airborne technologies offer interesting advantages, such as the free access to the manipulated sample.<\/p><p>In this work an efficient technique to easily generate high-quality structured acoustic beams in air is presented. This new approach eliminates reflection losses included in previously reported passive approaches that combine an acoustic source with a diffraction grating. This is possible by converting the grating into an emitter. To demonstrate the versatility of this approach, active spiral-shaped diffraction gratings were fabricated to generate AVB over a broad range of frequencies, i.e., from 70 kHz to beyond 300 kHz, in air. By varying the excitation frequency, a fine and continuous tuning of the focal length of the resultant AVB can be achieved, i.e., the beam can be axially steered while their spatial distribution is preserved. Experimental results from two grating prototypes are included: an Archimedean spiral able to generate simultaneous higher order Bessel beams with different topological charges along the propagation axis and a spiral-Fresnel Zone Plate that allows for sharply focused AVG. The experiments show a good agreement with simulations.\u00a0 The versatility and simplicity of the fabrication process make this technique highly suitable for emerging applications such as particle manipulation, imaging, and transfer of angular momentum to matter. A comparison between the different fabrication methods reported for AVB generation is included in this presentation.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-section elementor-top-section elementor-element elementor-element-91cf127 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"91cf127\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-0060e7d\" data-id=\"0060e7d\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-329d510 dce_masking-none elementor-widget elementor-widget-image\" data-id=\"329d510\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"300\" height=\"300\" src=\"https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/08\/Glauber-Silva-300x300.jpg\" class=\"attachment-medium size-medium wp-image-3187\" alt=\"Glauber Silva\" loading=\"lazy\" srcset=\"https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/08\/Glauber-Silva-300x300.jpg 300w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/08\/Glauber-Silva-1536x1536.jpg 1536w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/08\/Glauber-Silva-2048x2048.jpg 2048w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/08\/Glauber-Silva-150x150.jpg 150w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/08\/Glauber-Silva-768x768.jpg 768w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/08\/Glauber-Silva-1024x1024.jpg 1024w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-524c126 elementor-widget elementor-widget-heading\" data-id=\"524c126\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-medium\">Glauber Silva<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0ba414d elementor-align-center elementor-widget elementor-widget-dyncontel-popup\" data-id=\"0ba414d\" data-element_type=\"widget\" data-settings=\"{&quot;trigger&quot;:&quot;button&quot;,&quot;open_animation&quot;:&quot;enterFromTop&quot;,&quot;open_timingFunction&quot;:&quot;ease-in-out&quot;,&quot;open_delay&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:0,&quot;sizes&quot;:[]},&quot;close_animation&quot;:&quot;exitToBottom&quot;,&quot;close_timingFunction&quot;:&quot;ease-in-out&quot;}\" data-widget_type=\"dyncontel-popup.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t<div class=\"dce-button-wrapper\">\n\t\t\t\t\t\t\t\t\t<button class=\"dce-button-open-modal dce-button-popoup dce-animation-\"\n\t\t\t\t\t\t   data-target=\"dce-popup-0ba414d-7\"\t\t\t\t\t\t\t>\n\t\t\t\t\t\t\t\t\t\t\t<span class=\"dce-button-text\">Author Bio<\/span>\n\t\t\t\t\t\t\t\t\t\t<\/button>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"dce-popup-container dce-popup-container-0ba414d dce-popup-button\">\n\n\t\t\t\t\t\t\t\t\t<div id=\"dce-popup-0ba414d-7-background\" class=\"animated dce-modal-background-layer modal-background-layer\" data-dismiss=\"modal\" data-target=\"dce-popup-0ba414d-7\"><\/div>\n\t\t\t\n\t\t\t\t<div id=\"dce-popup-0ba414d-7\"\n\t\t\t\t\t class=\"dce-popup-0ba414d dce-modal modal-hide-esc modal-center modal-middle \"\n\t\t\t\t\t tabindex=\"-1\"\n\t\t\t\t\t role=\"dialog\"\n\t\t\t\t\t >\n\n\t\t\t\t\t<div class=\"modal-dialog animated\" role=\"document\" >\n\t\t\t\t\t\t<div class=\"modal-content\">\n\n\t\t\t\t\t\t\t<div class=\"modal-body\">\n\t\t\t\t\t\t\t\t<p>Glauber T.

In this talk, I will discuss the physical principles of 3D printed acoustofluidic devices used for cell levitation and aggregation. The cellular aggregate is formed in a controlled microenvironment at hundreds of micrometers above the device substrate. This is particularly suitable for Raman biospectroscopy, where signal interferences from the substrate are avoided. In turn, the Raman spectrum reveals the chemical bonds present in a cell. Also, the aggregation stability allows for individual cell Raman-spectrum acquisition. Acoustofluidic-assisted biospectroscopy of murine macrophages and red blood cells is illustrated with preferred quality over ordinary Raman strategies.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-section elementor-top-section elementor-element elementor-element-a8cec62 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"a8cec62\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-deeef1f\" data-id=\"deeef1f\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-98c065d dce_masking-none elementor-widget elementor-widget-image\" data-id=\"98c065d\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"284\" height=\"300\" src=\"https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/08\/David-Espindola-284x300.jpg\" class=\"attachment-medium size-medium wp-image-3188\" alt=\"David Espindola\" loading=\"lazy\" srcset=\"https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/08\/David-Espindola-284x300.jpg 284w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/08\/David-Espindola-768x812.jpg 768w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/08\/David-Espindola-969x1024.jpg 969w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/08\/David-Espindola.jpg 1019w\" sizes=\"(max-width: 284px) 100vw, 284px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2174dec elementor-widget elementor-widget-heading\" data-id=\"2174dec\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-medium\">David Espindola<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-e1714cb\" data-id=\"e1714cb\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div data-dce-advanced-background-color=\"#FEC629\" class=\"elementor-element elementor-element-ce10081 elementor-widget elementor-widget-heading\" data-id=\"ce10081\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h5 class=\"elementor-heading-title elementor-size-default\">Moderator<\/h5>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7cf3c8a elementor-widget elementor-widget-text-editor\" data-id=\"7cf3c8a\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Dr. David Esp\u00edndola was born in Chill\u00e1n, Chile, in 1986.

This talk will cover applications of two QUS methods, shear wave elasticity imaging and ultrasound backscatter spectroscopy, for the assessment of normal remodeling and damage of structurally complex tissues: the uterine cervix and the neonatal brain. In the cervix, shear wave elasticity imaging is investigated to analyze the frequency dependence of the phase velocity (dispersion) to learn about the structural basis of the cervical remodeling process during pregnancy. In the neonatal brain, ultrasound backscatter spectroscopy is being investigated as a potential tool for detecting cell death caused by different insults, such as long exposures to anesthetics. The talk will conclude with a discussion on the perspective for an extended application of these techniques.\u00a0<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-section elementor-top-section elementor-element elementor-element-e2665cb elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"e2665cb\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-2adf1c6\" data-id=\"2adf1c6\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-51f4ed3 dce_masking-none elementor-widget elementor-widget-image\" data-id=\"51f4ed3\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"200\" height=\"300\" src=\"https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/06\/HeadshotVerasonics-200x300.jpeg\" class=\"attachment-medium size-medium wp-image-2803\" alt=\"HeadshotVerasonics\" loading=\"lazy\" srcset=\"https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/06\/HeadshotVerasonics-200x300.jpeg 200w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/06\/HeadshotVerasonics-768x1152.jpeg 768w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/06\/HeadshotVerasonics-683x1024.jpeg 683w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/06\/HeadshotVerasonics.jpeg 1000w\" sizes=\"(max-width: 200px) 100vw, 200px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ed9bb32 elementor-widget elementor-widget-heading\" data-id=\"ed9bb32\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-medium\">Miguel Bernal<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c0eec4f elementor-align-center elementor-widget elementor-widget-dyncontel-popup\" data-id=\"c0eec4f\" data-element_type=\"widget\" data-settings=\"{&quot;trigger&quot;:&quot;button&quot;,&quot;open_animation&quot;:&quot;enterFromTop&quot;,&quot;open_timingFunction&quot;:&quot;ease-in-out&quot;,&quot;open_delay&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:0,&quot;sizes&quot;:[]},&quot;close_animation&quot;:&quot;exitToBottom&quot;,&quot;close_timingFunction&quot;:&quot;ease-in-out&quot;}\" data-widget_type=\"dyncontel-popup.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t<div class=\"dce-button-wrapper\">\n\t\t\t\t\t\t\t\t\t<button class=\"dce-button-open-modal dce-button-popoup dce-animation-\"\n\t\t\t\t\t\t   data-target=\"dce-popup-c0eec4f-9\"\t\t\t\t\t\t\t>\n\t\t\t\t\t\t\t\t\t\t\t<span class=\"dce-button-text\">Author Bio<\/span>\n\t\t\t\t\t\t\t\t\t\t<\/button>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"dce-popup-container dce-popup-container-c0eec4f dce-popup-button\">\n\n\t\t\t\t\t\t\t\t\t<div id=\"dce-popup-c0eec4f-9-background\" class=\"animated dce-modal-background-layer modal-background-layer\" data-dismiss=\"modal\" data-target=\"dce-popup-c0eec4f-9\"><\/div>\n\t\t\t\n\t\t\t\t<div id=\"dce-popup-c0eec4f-9\"\n\t\t\t\t\t class=\"dce-popup-c0eec4f dce-modal modal-hide-esc modal-center modal-middle \"\n\t\t\t\t\t tabindex=\"-1\"\n\t\t\t\t\t role=\"dialog\"\n\t\t\t\t\t >\n\n\t\t\t\t\t<div class=\"modal-dialog animated\" role=\"document\" >\n\t\t\t\t\t\t<div class=\"modal-content\">\n\n\t\t\t\t\t\t\t<div class=\"modal-body\">\n\t\t\t\t\t\t\t\t<p>Miguel Bernal received the degree in biomedical engineering from the School of Engineering of Antioquia, Medellin, Colombia.

Unfortunately, HFVI usually requires ultrasound systems with a large channel count to achieve rates in the kHz order. These systems are usually expensive which makes their use limited to a few laboratories around the world. In 2020, Verasonics introduced the concept of Sparse Random Aperture Compounding (SRAC) to help overcome this limitation. SRAC was developed for ultrasound systems with a significantly lower number of channels than elements in a matrix probe. The idea is to perform compounding of random apertures to balance image quality and frame rate. In the current work we studied the impact of random aperture optimization on the image quality and evaluated the compounding of complementary and non-complementary random apertures. While our previous study showed the benefits of using SRAC for HFVI, random aperture optimization is crucial to improve image quality while preserving high frame rates.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-section elementor-top-section elementor-element elementor-element-e4a3e2b elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"e4a3e2b\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-22bd5b0\" data-id=\"22bd5b0\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-0b1ddb9 dce_masking-none elementor-widget elementor-widget-image\" data-id=\"0b1ddb9\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"248\" height=\"300\" src=\"https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/06\/Roberto-Lavarello-248x300.png\" class=\"attachment-medium size-medium wp-image-2688\" alt=\"Roberto Lavarello\" loading=\"lazy\" srcset=\"https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/06\/Roberto-Lavarello-248x300.png 248w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/06\/Roberto-Lavarello.png 652w\" sizes=\"(max-width: 248px) 100vw, 248px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c9c9d7c elementor-widget elementor-widget-heading\" data-id=\"c9c9d7c\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-medium\">Roberto Lavarello<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-3f8355f\" data-id=\"3f8355f\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div data-dce-advanced-background-color=\"#FEC629\" class=\"elementor-element elementor-element-83102ce elementor-widget elementor-widget-heading\" data-id=\"83102ce\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h5 class=\"elementor-heading-title elementor-size-default\">Moderator<\/h5>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-662651b elementor-widget elementor-widget-text-editor\" data-id=\"662651b\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Roberto Lavarello received his B.Sc. degree in Electronics Engineering from the Pontificia Universidad Cat\u00f3lica del Per\u00fa in 2000, and his M.Sc. and Ph.D. degrees in Electrical and Computer Engineering from the University of Illinois at Urbana-Champaign in 2005 and 2009, respectively.

Also, the reciprocity of sources and receivers was evaluated as well as the computational complexity of the methods<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-section elementor-top-section elementor-element elementor-element-bf4ea64 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"bf4ea64\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-db785a7\" data-id=\"db785a7\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-8aa1627 dce_masking-none elementor-widget elementor-widget-image\" data-id=\"8aa1627\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"265\" height=\"300\" src=\"https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/06\/Chris-Korte-265x300.jpg\" class=\"attachment-medium size-medium wp-image-2708\" alt=\"Chris Korte\" loading=\"lazy\" srcset=\"https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/06\/Chris-Korte-265x300.jpg 265w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/06\/Chris-Korte-768x869.jpg 768w, https:\/\/2021.ieee-laus.org\/wp-content\/uploads\/sites\/48\/2021\/06\/Chris-Korte.jpg 877w\" sizes=\"(max-width: 265px) 100vw, 265px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a14af8a elementor-widget elementor-widget-heading\" data-id=\"a14af8a\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-medium\">Chris de Korte<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-be120bb\" data-id=\"be120bb\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div data-dce-advanced-background-color=\"#FEC629\" class=\"elementor-element elementor-element-c0128cd elementor-widget elementor-widget-heading\" data-id=\"c0128cd\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h5 class=\"elementor-heading-title elementor-size-default\">Moderator<\/h5>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-09479eb elementor-widget elementor-widget-text-editor\" data-id=\"09479eb\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p><span style=\"color: #202020;font-family: Arial, 'Helvetica Neue', Helvetica, sans-serif;text-align: justify\">Chris\u00a0L.\u00a0de\u00a0Korte\u00a0is a Professor of Medical Ultrasound Techniques at Radboud University Medical Center since 2015 and a professor of medical ultrasound imaging at the University of Twente since 2016.
