RF tissue heating of the Active Medical Implantable Devices (AIMD) is a well-known problem. However, due to the complex structure of the body, in vivo testing of the AIMDs’ heating under MRI cannot be verified with phantoms completely. Acute in vivo experiments damage the tissue and body’s thermoregulation response changes which can affect the measurements and investigation of the problems. Here, we propose a Temperature Sensor Implant setup to eliminate hyperacute effects of the surgery and enable real-time temperature monitoring of the tip of the implant during MRI examination
