A radiographic image detecting apparatus comprising operational amplifiers

摘要

The pixel unit 1 for a radiographic image detecting apparatus according to the invention comprises an input reset switch 200 and an output reset switch 300 that is able to selectively connect the radiation detector of a pixel unit 1 in the negative feedback channel of an operational amplifier 100. This allows for the production of an output signal without any delay caused by a displacement of electric charges from the radiation detector 10 to the operational amplifier 100.
