摘要： A radiographic apparatus removes lag-behind parts from radiation detection signals taken from an FPD as X rays are emitted from an X-ray tube, on an assumption that the lag-behind part included in each X-ray detection signal is due to an impulse response formed of exponential functions, N in number, with different attenuation time constants. The lag-behind parts are removed by using impulse responses corresponding to variations in the sensor temperature of the FPD. X-ray images are created from corrected radiation detection signals with the lag-behind parts removed therefrom.

摘要： A subtraction image is obtained, by a subtraction process (DSA process), from a live image and a mask image. A lag-behind part included in each X-ray detection signal is considered due to an impulse response formed of exponential functions. The lag-behind part is removed from each X-ray detection signal by a recursive computation to obtain a corrected X-ray detection signal. The live image and mask image are obtained from such corrected detection signals.

摘要： A radiographic apparatus removes lag-behind parts from radiation detection signals taken from an FPD as X rays are emitted from an X-ray tube, on an assumption that the lag-behind part included in each X-ray detection signal is due to an impulse response formed of a plurality of exponential functions with different attenuation time constants. The lag-behind parts are removed by using impulse responses of the FPD corresponding, for example, to an X-ray dose used in a fluoroscopic image pickup and an X-ray dose used in a radiographic image pickup. X-ray images are created from corrected radiation detection signals with the lag-behind parts removed therefrom.

X-ray images are created from the lag-free radiation detection signals.

摘要： In the radiographic apparatus according to this invention, when a radiographic mode designator 16 designates a non-standard radiographic mode, a signal corrector 15 uses defect information stored in one of non-standard image defect information memories 18B-18E for correcting X-ray detection signals outputted from an FPD 2. Since the pixel defect information for non-standard X-ray images is acquired by a pixel defect information converter 19 through a conversion from defect information for standard X-ray images stored in a standard image defect information memory 18A, it is unnecessary to collect output signals for pixel defect information acquisition from the FPD 2 all over again. As a result, abnormal X-ray detection signals due to defects of radiation detecting elements may be corrected promptly, regardless of how the radiation detecting elements are assigned to the pixels in the X-ray images.

摘要： A radiographic apparatus removes lag-behind parts from radiation detection signals taken from an FPD as X rays are emitted from an X-ray tube, on an assumption that the lag-behind part included in each X-ray detection signal is due to an impulse response formed of a plurality of exponential functions with different attenuation time constants. When a single attenuation time constant and intensity are provisionally set, checking is made whether an attenuation to a noise level of X-ray detection signals occurs in an X-ray non-emission state following an X-ray emission state. When the set attenuation time constant and intensity are found appropriate (OK), the impulse response having the single exponential function is determined valid. Corrected radiation detection signals are obtained by removing the lag-behind parts using the impulse response determined.

摘要： Although Cl (chlorine) is no longer supplied in the course of a first process in which a detecting layer formed by a polycrystalline film or a polycrystalline lamination film by vapor deposition or sublimation is formed, an additional source (e.g., HCl of Cl-containing gas) other than a source is supplied at the start or in the course of the first process. Thus, the detecting layer as the polycrystalline film or the polycrystalline lamination film of CdTe, ZnTe, or CdZnTe can be doped with Cl uniformly in a thickness direction from the start until the end of the first process in film formation. As a result, uniform crystal particles and uniform detection characteristics can be achieved.

摘要： A power supply apparatus for a detector of this invention provides a plurality of power supplies for the detector for detecting light or radiation, and includes a power output device capable of individually outputting the plurality of power supplies to be provided for the detector, a detection device for detecting a power supply state of a utility power source, a control device for carrying out an abnormal stopping process to stop the power supplies at the power output device in a predetermined order upon determination based on a result of detection by the detection device that an abnormality has occurred, and an electric storage device for supplying electric power to the control device, when the control device determines that an abnormality has occurred, to permit the control device to carry out the abnormal stopping process. Thus, without having a large-scale uninterruptible power supply system, the detector can be protected even when the electric power supply state from the utility power source becomes abnormal.
