MANADBS project

Deep brain stimulation (DBS) has been widely accepted as an effective treatment for movement disorders such as Parkinson Disease (PD), essential tremor or dystonia. During DBS, high-frequency (mostly 130Hz) electrical stimulation is applied to disrupt the abnormal information flow using multi-contact electrodes implanted in the structures of the brain responsible for the regulation of movement. Electrical stimulation is applied to anatomical structures measuring a few millimetres and errors in the position of the electrodes can lead to the massive therapeutic differences from undesirable side effects to treatment failure.The goal of Magnetic Navigation for DBS (MANADBS) project is to develop a functional demonstrator allowing position and orientation detection and real-time navigation, and being compatible with current surgical protocols.A preliminary work conducted at the Institute for Medical Engineering and Medical Informatics (IM2) has demonstrated the feasibility to track the position of DBS electrodes with an embedded 3D magnetic sensor [Quirin et…
