Abstract
The present invention provides a radiation detecting element and a radiographic imaging device that may reliably detect irradiation of radiation even when a region where radiation is irradiated is set narrowly. Namely, the present invention provides a radiation detection element and a radiographic imaging apparatus, in which radiographic imaging pixels and radiation detection pixels are provided at intersecting portions of scan lines and signal lines.
Claims18
A radiation detection element comprising:
- a plurality of scan lines that are provided in parallel to each other;
- a plurality of signal lines that are provided in parallel to each other, and that intersect with the scan lines;
- and
- a plurality of pixels that are provided at intersecting portions of the scan lines and the signal lines, the plurality of pixels including,
- a plurality of radiographic imaging pixels each including, a sensor section that generates charges based on irradiation of radiation or on illumination of light that has been converted from radiation, and a switching element that is turned ON and OFF according to a state of a control signal flowing in the scan line, wherein the sensor section is electrically connected to the signal line through the switching element, and an electric signals corresponding to the charges generated in the sensor section flows in the signal line according to the state of the control signal, and
- a plurality of radiation detection pixels each including the sensor section that is electrically connected to the signal line, wherein an electric signals corresponding to the charges generated in the sensor section flows in the signal line irrespective of the state of the control signal.
