Abstract

Our world is 3D and so is the patient. But visual camera observations are 2D. Advancements in digital imaging now enable capturing rich 3D information of our surrounding, transforming our ability to digitally perceive, present, and analyze data. By combining multiple data sources or frames in a video, we can create context-enhanced digital copies of the physical world as well as the patient - and apply data-driven interpretations and processing. Data sources reach from ceiling mounted cameras in the OR to endoscopic images or robot-mounted sensors. In this talk, we want to look into underlying core ideas of example 3D computer vision pipelines and investigate how these approaches can be used in clinical applications. As a basis for a discussion at this exciting interdisciplinary crossroad, we dive into the subtopics 3D digital reconstruction, data curation for XR, and robot-assisted surgery.

Abstract

Due to the rapid progress in developing experimental techniques, establishing and improving analysis methods is one of the major challenges in computational life sciences. For many analysis tasks, however, the limitations and performance of competing methods remain unknown, and there are no clear rules or guidelines for selecting the optimal analysis method. Benchmark studies have proven to be valuable tools for evaluating the performance and applicability of analysis approaches. However, they are often subject to methodological limitations and deficiencies, leading to potential bias in the results.

In my presentation, I will give an overview of novel approaches developed in my group in the context of mathematical modeling and omics analyses. In particular, I will summarize our ongoing efforts to improve the methodology of benchmark studies. By generally incorporating rigorous planning, design, and analysis principles in benchmark studies, we aim to promote the development of novel analysis approaches and the identification of decision rules for optimal method selection in practice. Especially in view of the enormous efforts to apply deep learning methods in all areas of research, reliable performance comparisons are of great importance.

Abstract

Bioimpedance analysis is an established non-invasive method that is already in clinical use for body composition measurement or electrical impedance tomography. However, novel instrumentation and signal processing approaches enable significant improvements of these applications as well as new measurement approaches. This presentation will give a brief insight into the theory of bioimpedance analysis and discuss instrumentation approaches. Subsequently, examples of new scientific measurement approaches will be presented. The focus will be on the detection of skeletal muscle contractions (impedance myography) and pulse wave detection (impedance plethysmography).
