Abstract

PROBLEM TO BE SOLVED: To provide a system for displaying an ultrasonic three-dimensional cross-section image, capable of obtaining a cross-section image having wide field angles without reducing the space and time resolutions of the cross-section image. SOLUTION: A cross section 48 in parallel with the bottom surface of a pyramid type area, obtained through three-dimensional scanning by an ultrasonic beam, and cross-sections 50, 52 in the diagonal direction of the bottom surface of the area 10, are planes which are orthogonal to each other. Three cutting surfaces, 54, 56, 58 composed of these three cross-sections are displayed. Since cutting surfaces 50, 52 are planes in the diagonal direction of the bottom surface of the area 10, the field angles thereof are made wider than those of the cutting surfaces formed through dividing each side of the bottom surface, so that cross- section images 56, 58 having respective wider field angles can be obtained.
