    摘要： A plurality of ultrasonic transducer elements are arranged on the top surface of a probe, which is a concave spherical surface, so that ultrasonic beams transmitted from the ultrasonic transducer elements will intersect at a point coincident with the center of curvature of a curve delineated by the top surface. At this time, the acoustic lines conically propagate over a region beyond the point of intersection. Namely, the ultrasonic beams transmitted from the ultrasonic transducer elements pass through the point of intersection coincident with the center of curvature, and then conically and three-dimensionally propagate over the region beyond the point of intersection. Thus, acoustic lines are three-dimensionally transmitted to a wide region beyond an intercostal part of a physiological body or any other narrow space, and echoes returned from the region are received. Consequently, the wide region can be three-dimensionally monitored.
