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).
