Abstract

The ultrasonic wave generated by an ultrasonic transducer mounted at the end of an insert assembly scans a region of scanning. Ultrasonic echo is received by the transducer. A video memory stores sequentially video data of a plurality of video frames or scanning durations. With a freeze operation is commanded, the degree of coincidence between data obtained at the start of scanning and at the end of the scanning is calculated, or the degree of coincidence between two identical sounding lines but with one scanning duration apart in time therebetween is calculated. The video of highest coincidence is displayed as a still video.
