The laboratory is developing specific sensors to acquire real-time information on patient movement during MRI examinations. The difficulty lies in the complex electromagnetic environment of MRI. Major adaptations are required to obtain MRI-compatible sensors. We have mainly developed sensors for electrophysiological and respiratory signals.
We are also developing experimental measurement and numerical simulation methods to control the risks associated with the presence of medical devices in MRI. These risks include attraction, heating, vibration and device malfunction.
