ABSTRACT:
A multi-dimensional visualization apparatus for observing tissue has a diagnostic apparatus (10) for producing ultrasonic tomographic image data with respect to respective parallel cross sections of tissue to be observed, an image memory (13a) for temporally storing the tomographic image data in the respective cross sections, fed from the diagnostic apparatus, and a computer (14). The computer has a detection function (S13, S14) for detecting layer surface positions in the respective cross sections of the tissue based upon the tomographic image data stored in the memory, to produce layer surface coordinate data indicative of the detected layer surface positions, a coordinate transformation function (S16) for converting the layer surface coordinate data of the respective cross sections into three-dimensional coordinate data, and a display function (S17, S18) for displaying both a three-dimensional image of the layer surface positions in the respective cross sections of the tissue based upon the converted three-dimensional coordinate data and the tomographic image of a desired cross section based upon the tomographic image data stored in the memory, on the same screen.
