Patent ID: 8541751

Claim:
A method of managing at least two radiation detectors of a radiographic image capturing apparatus, comprising the steps of: recognizing the positions of defective pixels of a plurality of manufactured radiation detectors; referring to the recognized positions of defective pixels and assembling at least two radiation detectors into the one radiographic image capturing apparatus in a superposed relationship, such that the defective pixels of the radiation detectors are not superposed one on the other in one pixel position; selecting two radiation detectors such that no defective pixels are superposed in a same pixel position by referring to the recognized positions of defective pixels; generating a plurality of region information tables corresponding to the respective manufactured radiation detectors, each of the region information tables registering therein positional information of first regions, which include defective pixels, and second regions, which are free of defective pixels, wherein the first regions and the second regions have the same pixel array, and wherein the step of selecting two radiation detectors comprises the step of selecting two radiation detectors from the manufactured radiation detectors, such that the first regions and the second regions are superposed one on the other when the two radiation detectors are stacked together, based on the region information tables; reflecting the position of a defective pixel, which is newly discovered in a regular or irregular defective pixel detecting process carried out on the radiographic image capturing apparatus, which incorporates the two radiation detectors stacked together, in the region information tables corresponding to the two radiation detectors; determining whether or not the first regions are superposed one on the other based on the region information tables corresponding to the two radiation detectors stacked together; and issuing a warning if it is judged in the determining step that the first regions are superposed one on the other.
