    摘要: Conventional reset ability is fixed of resetting an amplifier in a charge-to-voltage conversion amplifier. According to an imaging device of this invention, reset ability may be switched. For this purpose, a reset ability-switching function is provided for switching power consumption of the amplifier as reset ability of resetting an amplifier in the charge-to-voltage conversion amplifier, which may realize free switching of the power consumption as the reset ability and adaptability to various types of charge-to-voltage conversion. Accordingly, heat generation may be suppressed by switching power consumption to the lower one in the case where heat generation possibly increases.

    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.
