- 摘要：
PROBLEM TO BE SOLVED: To provide a radiographic apparatus which prevents imaging of a false image on a generated image by acquiring detection signals of a capacitor matrix while eliminating influence of apparent fluctuations in bias voltage.
SOLUTION: The radiographic apparatus comprises a radiation prohibiting section 7 that prohibits X-ray beam radiation from an X-ray tube 3 and a readout prohibiting means that prohibits a readout control section 8 from carrying out readout operation. When X-ray beam radiation from the X-ray tube 3 is prohibited by the radiation prohibiting section 7, a readout prohibiting section 9 prohibits starting of readout of detection signals. By doing so, X-ray beam radiation and readout of detection signals of an FPD 4 correspond with each other one by one. As a result, bias voltage becomes apparently constant for every time one row of the capacitor matrix is readout. With such a configuration, a X-ray radiographic image from which influence of X-ray beam is removed is acquired.
