<P>PROBLEM TO BE SOLVED: To provide a radiographic image detecting apparatus and a radiographic image capturing system for preventing an increase/decrease of light receiving sensitivity of photoelectric conversion elements even when a bias current amount flowing to the photoelectric conversion elements increases/decreases corresponding to the dose of radiation. <P>SOLUTION: Since a current mirror circuit 100 is used as current detection means 62 for detecting a bias current I1 of a photoelectric conversion element 48, a voltage on the input side (diode connection side) of the current mirror circuit 100 is hardly changed even when the bias current I1 is changed. Thus, voltage drop does not occur during emission of radiation, a bias voltage of the photoelectric conversion element 48 is held roughly fixed, and the light receiving sensitivity is not increased/decreased. <P>COPYRIGHT: (C)2012,JPO&INPIT |
