概要

In this paper, medical devices for assisting therapy under MRI guidance are introduced. Recent advances of the interventional MRI (Open MRI surgery) have been promoted to achieve minimally invasive surgery. As basic components for MRI compatible devices, three researches are introduced : a surgical manipulator for needle placement, a pneumatic saw-tooth stepping motor, and a non-metal display inside the MR gantry. A mere introduction of the conventional robot/electrical & mechanical devices should be avoided because it will probably disarrange the strong magnetic field in MR environment and cause image distortions. The application for therapy and the required image resolution are described and some advanced MRI compatible device researches are also discussed.
