ABSTRACT:
A method and apparatus are provided for processing ultrasonic diagnostic image information acquired in a plurality of scan planes for presentation as a three dimensional display of a volumetric region of the body. The image points in each scan plane are repositioned by approximating the rotation and translation of the scan plane in correspondence with the angle from which the volumetric region is to be viewed. This approximation is accomplished using conventional scan conversion processors by scaling the spatial coordinates of the original ultrasonic image in one or more dimensions and translating the image in one or more directions in correspondence with the viewing angle. A plurality of such scaled and translated images are accumulated and displayed in a combined three dimensional image presentation.
