Patent ID: 8870775

Claim:
An ultrasonic diagnostic apparatus comprising: an ultrasonic probe in which a surface emits ultrasonic waves and rotates the ultrasonic wave emitting surface centering on an axis included in the ultrasonic wave emitting surface; a generating unit configured to generate a plurality of ultrasonic cross-sectional images at a plurality of rotation angles when the ultrasonic wave emitting surface in the ultrasonic probe is rotated; an image display; an angle information memory; and a regenerating unit configured to save, to the angle information memory, information on a rotation angle when generating a first ultrasonic cross-sectional image in response to a condition being satisfied, regenerate the first ultrasonic cross-sectional image at the rotation angle by rotating the ultrasonic wave emitting surface of the ultrasonic probe based on the information of the rotation angle stored in the angle information memory when an instruction to regenerate the first ultrasonic cross-sectional image is received at a state of generating an ultrasonic cross-sectional image at an angle different from the rotation angle information saved on the angle information memory, and regenerate the first ultrasonic cross-sectional image on the image display, wherein the condition corresponds to a rotation angle of the ultrasonic wave emitting surface being maintained for a predetermined period of time or the rotation angle of the first ultrasonic cross-sectional image being changed.
