Abstract: A radiographic apparatus includes a columnar crystal phosphor which converts X-rays into visible light, a photodetector which converts the visible light into an electrical signal, and a case (a case lid and case main body) which houses the columnar crystal phosphor and photodetector. A buffer member which buffers a force from outside the case (the case lid and case main body) and a highly rigid member which has higher rigidity than that of the columnar crystal phosphor are arranged between the case (the case lid and case main body) and columnar crystal phosphor.

Abstract: An X-ray sensing apparatus with which reduction is achieved in the amount of electric power consumed to drive an X-ray sensor, including: a sensing unit including a plurality of photoelectric conversion elements each converting light into an electric signal; a driving range designating unit for designating a driving range for driving each of the plurality of photoelectric conversion elements included in the sensing unit; a drive unit for driving the photoelectric conversion element in the driving range designated by the driving range designating unit; a reading range designating unit for designating a reading range of the photoelectric conversion element driven by said driving unit; and a signal reading unit for reading out an output of the photoelectric conversion element in the reading range designated by the reading range designating unit.

Abstract: In step S203, an FPN image is obtained before radiography. In step S204, uniformity of the values of pixels contained in the FPN image is determined by using the values of the pixels contained in the FPN image.

Abstract: A radiography apparatus with a function for evaluating image quality is provided. To accomplish this, the radiography apparatus includes a radiating-generating unit for emitting radiation, an imaging unit for converting the radiation into image data, a measuring unit for measuring an image-quality evaluating value of the image data, and a determining unit for determining the image quality of the imaging unit based on a plurality of image-quality evaluating values of the image data acquired at a plurality of points in time, where each image-quality evaluating value corresponds to the image data acquired at one of the points in time.
