Incompatibility of therapeutic implants and medical devices with key diagnostic tools such as Magnetic Resonance Imaging (MRI) systems has impaired widespread application of implantable electronics and neuromodulation systems. As a result, these devices are considered as the last therapy option, despite their significant therapeutic or health-check benefits for the patient. With a consortium of 21 partners from 7 EU countries, the DeNeCoR project aimed at addressing this incompatibility issue and demonstrating the coexistence of therapeutic and diagnostic systems by the development of new MR compatible sensors and devices. As part of this project Fraunhofer ENAS, in collaboration with other partners, has developed a MR compatible micro endoscope capable of simultaneously capturing live camera as well as ultrasound images of the target tissue. This demonstrator is intended as an intraoperative diagnostic tool for brain surgery and would help the surgeon to better visualize small areas of the target tissue and more accurately plan the therapeutic procedure.
