Abstract

An ultrasonic diagnostic apparatus including an ultrasonic probe, and a transmitter/receiver section for scanning a three dimensional region of a detected object with ultrasonic beams by driving the ultrasonic probe and receiving echo signals reflected from an object within the three dimensional region. An organ of the object is detected and three dimensional figure image data depicting a figure of the detected organ in the three dimensional region are formed based on the received echo signals. Also determined from the received echo signals is a function of the detected organ, for example by obtaining and thresholding tissue Doppler image data or harmonic image data, and based on the determined function, three dimensional functional image data depicting the function of the detected organ in the three dimensional region are formed. The three dimensional figure image data are displayed by a wire frame method, a bull's eye map method and/or a semi-transparent surface model method. The displayed three dimensional figure image of the detected organ is combined with display of the functional image of the organ, with neither displayed image obstructing the other displayed image so that the figure image of the organ can be utilized as a positioning guide for selection of the position of the functional image of the organ.
