10:00 - 11:00 Open Problems in Cardiac Ultrasound
Speaker: Andrej Varchola & Alexey Karimov (Siemens Healthineers)
Room: 335
Andrej Varchola is a software engineer and technology field owner specializing in 4D visualization at Siemens Healthineers Ultrasound in Košice, Slovakia. He earned his Master's degree in Digital Signal Processing from the Slovak University of Technology and holds a PhD in Medical Visualization from the Vienna University of Technology. Andrej has successfully transitioned his academic expertise into the industry, focusing on research and development for mission-critical software. His career highlights include key contributions to several notable projects: 1) Developing HDlive rendering for realistic fetal imaging at GE Healthcare during his PhD studies. 2) Contributing to the dual-energy CT imaging system, Somatom Force, at Siemens Healthcare. 3) Visualizing data for the statistical validation of Honda's SAE Level 3 Automated Driving System. 4) Enhancing clinical applications for the Acuson Origin cardiovascular ultrasound system at Siemens Healthineers. Andrej's work bridges the gap between cutting-edge technology and practical medical applications, driving advancements in imaging and diagnostics.
Alexey Karimov is a software engineer in the Ultrasound division of Siemens Healthineers in Vienna, Austria. He received his PhD degree from the Technical University of Vienna, working in the fields of medical visualization and real-time volume rendering. In his current position, he aims to integrate advanced rendering and visualization methods into ultrasound systems deployed in clinical environments.

Abstract: Ultrasound imaging has always been a special case in the medical domain, given that it delivers images in real-time. This combined with characteristic noise and artifacts poses a challenge to producing clinically relevant data. The newest AI algorithms come here to aid the decision process with detection, labeling, assisted navigation, and report generation. As anatomical models of heart structures are inferred and available in real time, the need for advanced visualization techniques arises. Volume rendering alone does not suffice the requirements of the field, because many more data elements are present. Seamless integration of mesh models, measurement results, and inferred anatomical labels and features are expected from the upcoming generation of rendering/visualization pipelines in ultrasound.

Abstract: Diffusion MRI tractography reconstructs white matter tracts in the human brain from noninvasive measurements, and is widely used in surgery planning and neuroscience. However, tractography is affected by various types of uncertainty, caused by measurement noise, loss of information through partial voluming, and the need for simplifying assumptions during data analysis. This talk will provide an introduction to diffusion MRI tractography, highlight some of its applications, and discuss approaches towards more reliable interpretation via uncertainty visualization and uncertainty reduction.
