PURPOSE:To perform rotary scanning by keeping the direction of the probe mounted on a rotary part on a revolution plane constant by providing a plurality of links connecting a frame and a mounting body in a relatively movable manner. CONSTITUTION:An apparatus is equipped with a frame 2, a mounting plate 110 for mounting a probe 28 and three links 88, 90, 92 connecting the frame 2 and the mounting plate 110 in a relatively movable manner and the links 88, 90, 92 are mounted to the frame 2 at one ends thereof in a freely rotatable manner and also mounted to the mounting plate 110 at the other ends thereof in a freely rotatable manner so as to be capable of rotating in a state keeping mutual parallel relation to the frame. By this constitution, the apparatus allows the ultrasonic probe 28 to rotate in the direction reverse to revolution at the angle equal to revolution in a revolution system. By this method, the rotation in the direction of the probe 28 due to revolution is negated and the probe 28 becomes a state holding the same posture without generating revolution to a non-rotary inertia system. By this method, the direction of the probe mounted to the rotary part on a revolution plane is kept constant to make it possible to perform rotary scanning. |
