The technology of radiation imaging plays an important role in the area of no-bug diagnosis. Theprinciple is that the absorbed dose amount is different when rays go through objects with differentmaterial or thickness. According to the through ray intensity, we can get the characteristic picture ofdiagnostic objects. For this subject, the ray is from a ~(60)Co point irradiation source. 256 detector cellsreceive ray that pass through diagnostic objects. Two dimensions picture is displayed after amplify and
