Sectional image photography system and method thereof
First Claim
1. A sectional image photography system comprising:
- a mounting table adapted to receive an object to be examined;
a radiation projector for projecting a radiation toward an object being examined, the radiation being projected at a same portion of said object at a same level from different locations;
a flat-type plane radiation detector for obtaining a plurality of partial radiation images formed from the radiation transmitted through a same portion of the object at a same level from different locations while the object remains stationary relative to the radiation projector, in the form of electrical image signals; and
an image processor for composition-processing the partial radiation images obtained by the plane radiation detector into a sectional image of a desired section of the object.

Abstract
A sectional image photography system includes a mounting table adapted to receive an object to be examined; a radiation projector for projecting a radiation toward an object being examined, the radiation being projected at a same level from different locations; a plane radiation detector for obtaining a plurality of partial radiation images formed from the radiations transmitted through the object in the form of electrical image signals; and an image processor for composition-processing the partial radiation images obtained by the plane radiation detector into a sectional image of a desired section of the object. Here, X-rays are used as the radiation. The plane radiation detector has a plurality of plane radiation detectors which are disposed to correspond to the radiation projected from different locations of the radiation projector. Accordingly, since the radiation images transmitted through the object are directly obtained by the plane radiation detectors, there is no radiation image distortion. Further, since there is no need to employ a driving mechanism, the structure of the product is simplified and the reliability is increased.
