Patent ID: 6911996

Claim:
A fluoroscopy image apparatus, comprising: two-dimensional radiation sensor arrays formed of photoelectric conversion elements for outputting charge signals corresponding to an incident amount of radiation, switches arranged in a matrix form under the radiation sensor arrays and connected to the photoelectric conversion elements, a gate drive circuit connected to the switches for turning on the respective switches in case of reading out the charge signals, a readout amplifying circuit connected to the sensor arrays for reading out the charge signals stored in respective pixels, a control circuit connected to the gate driver circuit and the readout amplifying circuit for controlling the same, a digital-to-analog switching circuit connected to the control circuit for switching between a digital video control and an analog video control so as to use one of the controls, a TV reference signal circuit connected to the control circuit and the gate drive circuit for controlling the gate drive circuit in the analog video control, said TV reference signal circuit having a horizontal scanning/synchronization pulse waveform generating circuit and a vertical scanning/synchronization pulse waveform generating circuit, and a picture signal superimpose circuit connected to the TV reference signal circuit and the readout amplifying circuit, said gate driver circuit, upon actuating the analog video control, being driven by signals from the TV reference signal circuit for taking out picture signals from the radiation sensor arrays through the readout amplifying circuit and said picture signal superimpose circuit superimposing the picture signals on the signals from the TV reference signal circuit by synchronizing with the signals from the TV reference signal circuit to thereby output a TV analog video signal.
