Système de tracking électromagnétique pour l’implantation d’électrodes de stimulation cérébrale profonde utilisant des capteurs magnétiques intégrés

Deep Brain Stimulation (DBS) is a key treatment for neurological and psychiatric disorders like Parkinson’s disease or essential tremor. Despite its success, challenges remain, including precise electrode placement and optimal stimulation parameters. Traditional methods lack real-time feedback, necessitating innovative solutions. This thesis presents an electromagnetic tracking (EMT) system for DBS localization. Using quasi-static magnetic fields and integrated magnetometers, the system aims for high spatial and angular resolution. Experimental results show reliable tracking with 1.7 mm and 0.9° error, outperforming commercial EMT systems. It also integrates seamlessly into surgical workflows, reducing errors linked to stereotactic distortions. Additionally, a tailored registration-free method simplifies DBS procedures, reducing workload while ensuring accurate electrode visualization. By tackling technical and clinical challenges, this research advances neurosurgical technology, enhancing precision, minimizing risks, and improving patient outcomes.
