摘要： A lamp emits pulse-shaped visible light when a wait period begins. If a radiation emission switch is not pressed in the wait period, X-ray radiation is not emitted from an X-ray source, and no charges are accumulated in photoelectric conversion elements of an X-ray imaging apparatus. In a non-read period, although signals are sequentially read from the photoelectric conversion elements, an output signal does not change. When the radiation emission switch is pressed in synchronization with a radiation-induced signal in a certain wait period, the X-ray source emits X-rays. After irradiation of X-rays, a photoelectric conversion period transitions to an actual read period. In the photoelectric conversion period, X-rays are emitted and transmitted X-ray information of a patient are accumulated in the photoelectric conversion elements of the X-ray imaging apparatus. In the actual read period, the accumulated information is read.

摘要： A radiography apparatus includes a conversion unit having conversion elements arranged in a row-column pattern to convert radiations into an electrical signal. In an object-image reading operation, the conversion unit detects an object image based on illuminated radiations, and a drive circuit drives the conversion unit so as to allow the conversion unit to output a signal based on the object image. In an offset-data reading operation, the conversion unit detects offset data in a period when the radiations are not illuminating, and the drive circuit drives the conversion unit so as to allow the conversion unit to output a signal based on the offset data. When the numbers of lines driven concurrently by the drive circuit in the object-image reading operation is represented by n (equal to 1 or greater) and the numbers of lines driven concurrently by the drive circuit in offset-data reading operation is represented by m, the drive circuit controls the conversion unit so as to satisfy the expression: n

摘要： When performing an offset correction, without lowering an image quality of the radiographed image data, a prompt radiographing is realized. Hence, a memory 105 stores a first image data for offset correction generated by performing an interlace scanning of the driving lines of odd rows only in a driving circuit unit 103. A memory 106 stores a second image data for offset correction generated by performing the interlace scanning of the driving lines of even row only in the driving circuit unit 103. A processing unit 108 synthesizes the first image data for offset correction and the second image data for offset correction, thereby to generate an image data for offset correction of one frame portion, and an arithmetic operation unit 109 performs an arithmetic operation processing on the radiation image data stored in a memory 107 by using the image data for offset correction of one frame portion synthesized and generated, thereby to perform the offset correction of the radiation image data.
