<p><P>PROBLEM TO BE SOLVED: To provide a radiation image detector and a radiographic imaging system which starts the reading of electric signals immediately after the completion of radiation in order to reduce noises for protecting the image quality from deterioration and suppresses extra-electric power consumption. <P>SOLUTION: The radiation image detector 1 includes a plurality of photoelectric conversion elements 7 to generate electric charges by the radiation, an amplification circuit 19 to amplify the electric signal read by the photoelectric conversion elements 7 through a signal line 6, a bias line 9 to supply reversed bias voltage to each photoelectric conversion element 7, a power source 15 to apply reversed bias voltage to the photoelectric conversion elements 7 through the bias line 9, a current detection means 14 to detect the current flowing through the bias line 9, and a control means 16 to set up the gain of the amplification circuit 19 before it begins the reading of electric signals on the basis of the current value detected by the current detection means 14 during the radiation. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
