4.	Development in relation to 3D Ultrasound

Aurélie Sarcher is the Principal Investigator of the OPTIMUS project : Open-Platform for Three-dimensional Imaging of Muscle using UltraSound. She has developed innovative methodologies for 3D freehand ultrasound imaging, leveraging existing open-source solutions. Her expertise spans system integration, from configuring hardware setups to creating user-friendly protocols for research and clinical applications. She has applied these techniques to investigate muscle-tendon unit lengths, and muscle volumes and shapes in sarcopenia and neuromuscular pathologies in clinical populations. Her work has supported international collaborations with renowned institutions (KU Leuven, Norwegian School of Sport Sciences, and others) and contributed to creating accessible educational resources shared via platforms like GitHub.
