Abstract. We present the proof-of-concept prototype of a prostate biopsy robot
to be used inside a conventional high-field MRI scanner. A three degree-of-
freedom (DOF) mechanical device translates and rotates inside the rectum and
enters a needle into the body, and steers the needle to a target point pre-selected
by the user. The device is guided by real-time images from the scanner. Net-
