a processor comprising hardware, the processor being configured to:
acquire a first echo image from a first ultrasonic wave acquired by an ultrasonic probe in which a target tissue is displayed on a central axis,
acquire a second echo image from a second ultrasonic wave acquired by the ultrasonic probe obtained by scanning a cross section different from the first echo image at a reference position of the ultrasonic probe from which the first echo image was acquired, and
compare a central axis of the second echo image with a position of the target tissue in the second echo image;
wherein the processor is configured to detect a difference in the position of the target tissue in the second echo image with respect to the central axis of the second echo image.
