Abstract
A scanning range of an object under examination is divided into m pieces (m is an integer equal to or more than 2) in a subscanning direction. One measurement condition or one parameter is set in m steps, and an ultrasonic measurement is performed on the object under examination while allotting successively the m-stepped measurement conditions or the m-stepped parameters to the respective scanning regions divided in the subscanning direction. A plurality of measurement images obtained under the m-stepped measurement conditions are displayed so as to permit comparison on a screen, and one of the m-stepped measurement conditions or m-stepped parameters which corresponds to an image selected from the displayed screen is set as the measurement condition.
