Document Type and Number:
WIPO Patent Application WO/2005/011499
Kind Code:
A1
Abstract:
A tomogram constituting system comprising a means for binarizing respective x-ray images from a plurality of different directions of a subject photographed by a x-ray system to form a plurality of binarized image, a means for setting scanning lines moving sequentially in a specified direction at mutually corresponding positions of the plurality of binarized images formed by the binarized image forming means, and a means for constituting a tomogram by reversely projecting the pixel points of the plurality of binarized images at the sequentially moving position of the scanning line set by the scanning line setting means.
