three-dimensional ultraschallabtaster

摘要

Three-dimensional ultrasonic scanner for acquiring data within an area of a living body to be examined comprises an array transducer unit (30), composed of a plurality of transducer elements (30a) arranged in line one after another inside a scanner case (22). The electronic scanning of this array transducer produces a two-dimensional scanning plane. In addition, a swinging mechanism (36,40,42) is provided for mechanically oscillating the transducer unit in a direction normal to the orientation of the array of transducer elements. thereby forming a three-dimensional data acquisition area within the living body. The swing angle of the transducer unit (30) is detected by an angle detector (44). IMAGE
