Patent ID: 7463717

Claim:
An X-ray detector system comprising: an X-ray source, a scintillating material layer deposited on an optical transmission plate, a rod lens array, and an image sensor array; wherein when a test specimen is exposed to an X-ray beam from said X-ray source, said X-ray beam passes through the test specimen and excites said scintillating material layer proportionally to X-ray density patterns of the test specimen, and a converted optical image from said scintillating material layer is focused by said rod lens array onto said image sensor array, a reproduced image of the test specimen thereafter being read out of said image sensor array; and wherein an optical path passing through said optical transmission plate, said rod lens array, and said image sensor array is offset by an acute angle relative to a centerline of an X-ray flux path from said X-ray source, such that detecting components of said X-ray detector system are removed from said X-ray flux path.
