RADIATION DETECTION PANEL, RADIATION IMAGING DEVICE, AND IMAGE DIAGNOSTIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a radiation detection panel capable of outputting a signal for generating an accurate pixel signal regardless of the performance of a conversion unit.SOLUTION: A detection circuit that outputs a signal used for generating a pixel signal includes (1) a first output circuit that outputs a signal due to afterglow and (2) a second output circuit that outputs a signal including both a signal based on radiation emission and a signal due to afterglow. Transistors using an oxide semiconductor material for a channel formation region are used as some transistors included in the first and second output circuits. In the radiation detection panel having this structure, the signal (a first signal or a second signal) can be held in each output circuit; and therefore, after all output circuits hold the signal (the first signal or the second signal), the first signal and the second signal can be sequentially output from detection circuits.
