ABSTRACT:
An ultrasonic imaging apparatus includes an ultrasonic transducer having a matrix of a plurality of ultrasonic transducer elements, and a transmitter/receiver circuit for driving the ultrasonic transducer elements with delay control so that the ultrasonic transducer selectively generates ultrasonic beams in X and Y scanning directions. A marker is set in a tomographic image obtained by scanning a subject in the X direction. The subject is scanned in the Y direction along the marker. A section image corresponding to the marker is output.
