Radiographic imaging device

摘要

The present invention provides a radiographic imaging including, provided at an insulating substrate, sensor portions for radiation detection that generate charges due to receive radiation or light converted from radiation, first signal lines that are connected to the sensor portions for radiation detection and through which flow electric signals that correspond to the charges generated at the sensor portions for radiation detection, and second signal lines having a substantially same wiring pattern as the first signal lines. Detection of radiation is carried out on the basis of a difference between an electric signal flowing through the first signal line and an electric signal flowing through the second signal line, or a difference between values of digital data obtained by digitally converting an electric signal flowing through the first signal line and an electric signal flowing through the second signal line, respectively.

1. A radiographic imaging device, comprising:
a plurality of pixels disposed in a matrix, each pixel including a sensor portion that generates charges based on irradiation of radiation or on illumination of light that has been converted from radiation, and a switch element for reading out the generated charges; a plurality of first scan lines, connected to the switch elements included in pixels that have been employed as radiographic imaging pixels among the plurality of pixels, and through which control signals for switching the switch elements flow; a plurality of second scan lines, connected to the switch elements included in pixels that have been employed as radiation detection pixels among the plurality of pixels, and through which control signals for switching the switch elements flows; a plurality of signal lines, connected to the switch elements, and through which electric signals flow, corresponding to the charges that have been generated in the pixels, in accordance with a switching state of the switch elements; and a detecting section that, when any one of the signal lines to which the radiation detection pixels are connected is defined as a first line and any one of the signal lines to which the radiation detection pixels are not connected, or at which a number of the connected radiation detection pixels is smaller than at the first line, is defined as a second line, detects radiation on the basis of a difference between an electric signal flowing through the first line and an electric signal flowing through the second line, or a difference between values of digital data obtained by digitally converting an electric signal flowing through the first line and an electric signal flowing through the second line, respectively, wherein four adjacent pixels of the plurality of pixels comprise one radiation detection pixel and three radiation imaging pixels.
