Patent ID: 7932500

Claim:
A radiation image detection method for detecting from a radiation image detector including a charge generation layer that generates charges by receiving radiation and a detection layer stacked on top of another, the detection layer including: multitudes of pixels, each having a collection electrode for collecting the charges generated in the charge generation layer, a capacitor for storing the charges collected by the charge collection electrode, and a TFT switch for reading out the charges stored in the capacitor; multitudes of scanning lines for switching ON/OFF the TFT switches; and multitudes of data lines for transferring the charges stored in the capacitors, an analog image signal of each of the pixels flowing out through each of the data lines by sequentially switching ON the TFT switches connected to each of the scanning lines on a scanning line-by-scanning line basis, and converting the detected analog image signal to a digital image signal and outputting, wherein the method further comprises the steps of: detecting an analog leak level flowing out through each of the data lines with the TFT switches connected to each of the scanning lines being switched OFF each time before switching ON the TFT switches on a scanning line-by-scanning line basis; and correcting the analog image signal based on the leak level prior to the conversion.
