Abstract

Abstract An ultrasonic transducer element (l30) is supported by a member (l20). The transducer element and the supporting member are disposed within a casing (l00) filled with ultrasonic wave propagation medium (l50). At least part of the casing forms an ultrasonic wave transmission window. In a first case, the supporting member (l20) is rotatable about a first axis (A) and about a second axis (B), and the position of the supporting member is detected (20). In a second case, the casing (30l) has a first portion (304) accommodating the transducer element (306) and the supporting member (307) and a second portion (303) extending in rear of the first portion and being narrower than the first portion, and the transducer element is allowed to emit and receive ultrasonic wave to and from a region extending in front of the casing with respect to a direction of insertion of the casing into a body to be examined. In a third case, a sensor (322) detects at least one condition related to operation of a mechanism driving the supporting member.
