摘要： A light or radiation image pickup apparatus comprises a first arithmetic unit 50 for calculating a first arithmetic value by subtracting a first offset signal from a main signal, a second arithmetic unit 51 for calculating a second arithmetic value which is a difference between a second offset signal and the first offset signal, and a correcting unit 52 for correcting the first arithmetic value calculated by the first arithmetic unit 50, by using the second arithmetic value calculated by the second arithmetic unit 51 and corresponding to a period of the same length as a period from the first offset signal to the main signal used in the operation in the first arithmetic unit 50. The first arithmetic value is corrected to remove noise components due to leakage of charge signals accumulated during the period from the first offset signal to the main signal. It is thus possible to reduce deterioration of image quality due to leaks of charge signals accumulated in X-ray detecting elements 11 (leakage currents) and prevent an extended imaging time.

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： An FPD controller controls a flat panel X-ray detector (FPD) to perform a reading operation for reading carriers (charge information) and a reset operation for resetting and discarding the carriers, during a frame cycle from a reading point of time for reading charge information collectively from a predetermined read area (i.e. an in-field of 2,048×2,048 pixels) to a reading point of time for reading charge information collectively from a next predetermined read area. This control can reduce the influence of the preceding predetermined read area.

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： An apparatus using a two-dimensional radiation sensor for acquiring X-ray penetration images or the like. A monitoring radiography is performed with a small dose before a production radiography. A radiographic condition for the production radiography, specifically a radiation emitting period or a tube current of a radiation generator, is computed based on a ratio between a quantity of charges in a region of interest collected from the two-dimensional radiation sensor in time of the monitoring radiography and a desired quantity of charges in the region of interest in time of the production radiography. The production radiography is carried out based on a result of the computation to acquire a high quality image.

This is formed separately from a semiconductor thick film. The semiconductor thick film and readout pattern constitute a flat panel X-ray detector (FPD) is mounted in a case to form a unit. A weight reduction is achieved by using the semiconductor thick film in place of a conventional glass substrate. The FPD manufactured in this way is free from great restrictions in time of transport and use.
