ABSTRACT:
Continuous tomographic image data obtained by a tomographic image forming unit such as an X-ray CT scanner is stored in a two-dimensional image memory under the control of a control computer. A two-dimensional space filtering processor, a two-dimensional affine transformation processor and a two-dimensional image addition processor are connected to the control computer and execute two-dimensional affine transformation, two-dimensional image addition and two dimensional space filtering of the tomographic image data, so that a pseudo three-dimensional reprojected image is obtained.
