Abstract: The ultrasonic imaging apparatus of the present invention is provided with a 3-dimensional image construction unit configured to construct a 3-dimensional image using plural ultrasonic tomographic images obtained when the ultrasonic probe is moved in a direction intersecting the direction of the ultrasonic tomographic images; and an ultrasonic probe moving direction setting unit configured to set the moving direction of the ultrasonic probe, using an ultrasonic tomographic image displayed on the screen of the display unit as a reference, in either a first direction which intersects with the direction of the tomographic image or a second direction of opposite orientation to the first direction; wherein the control unit controls the arrangement order of the plural ultrasonic tomographic images in the 3-dimensional image constructed in the 3-dimensional image construction unit according to the moving direction of the ultrasonic probe set by the moving direction setting unit of the ultrasonic probe.

Abstract: Previously captured three-dimensional image data of a subject from which a reference image is extracted are provided in the form of time-series volume data 14, 15 composed of two-dimensional image data groups which are recorded over at least one period of a periodically moving organ of the subject, with time-phase information of a biological signal of the subject added thereto. Two-dimensional image data whose time-phase information is identical with the time-phase information of the biological signal of the subject at the time when an ultrasonic image is captured are extracted from the three-dimensional image data so as to provide the reference image.
