Abstract
An ultrasonic diagnostic apparatus in which ultrasonic waves are transmitted into the subject, the ultrasonic waves reflected within the subject are received to obtain received signals, and an image is produced in accordance with the received signals thus obtained. Several reception scanning lines are formed in a transmission ultrasonic beam. Several images thus obtained are superimposed on one another or combined together. Using this device deterioration of the picture quality due to multiple reflections or multiple echoes is prevented.
