Abstract
An ultrasonic transducer element is supported by a member. The transducer element and the supporting member are disposed within a casing filled with ultrasonic wave propagation medium. At least part of the casing forms an ultrasonic wave transmission window. In a first case, the supporting member is rotatable about a first axis and about a second axis, and the position of the supporting member is detected. In a second case, the casing has a first portion accommodating the transducer element and the supporting member and a second portion 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 resepct to a direction of insertion of the casing into a body to be examined. In a third case, a sensor detects at least one condition related to opreation of a mechanism driving the supporting member.
