Sectional image photography system and method thereof

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 plurality of plane radiation detectors, which are disposed to correspond to the radiation projected from different locations of the radiation projector through a same portion of said object at said same level, 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, 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.

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;
• 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;
• and
• a plane radiation detector vertically disposed below the mounting table.

A method for obtaining a sectional image by using a sectional image photography system comprising the steps of:

• a) placing an object to be examined on a mounting table of the sectional image photography system, and focusing a certain section of the object at a certain height at a focus surface of the sectional image photography system;
• b) projecting radiation generated from a radiation projector with respect to an object being examined from at least two locations on a circumference of the radiation projector;
• c) obtaining at least two radiation partial images transmitted through the object from said at least two locations in the form of electrical image signals by using a flat-type plane radiation detector while the object is stationary relative to the radiation projector;
• and
• d) obtaining the sectional image by processing at least two radiation image signals which are obtained by the plane radiation detector.
