In this paper, we try to develop a miniaturized ultrasonic angina-pectoris scope, namely, miniaturized IVUS which is rotated by another ultrasonic micro motor for the observation of cerebral thromboses in brain vessels. As a first step of research, a prototype of IVUS with 3 mm outer diameter and 10 mm length has been developed and its torque-rotational speed characteristic was examined. And the principle to detect cerebral thromboses by sending ultrasonic sound to the radius direction of a blood vessel and catching its reflection while it is rotated by a micro motor was proposed and its fundamental characteristics were verified.
