Abstract
A radiographic imaging apparatus includes, in an image capturing region in which multiple pixels for obtaining radiological image data are arranged in rows and columns, a pixel array including a detection pixel group of a plurality of detection pixels for detecting the radiation dose, a control unit configured to control the image capturing, an image capturing unit configured to capture an image taken with the control unit, and an image-capturing-termination determination unit configured to terminate the image capturing at the image capturing unit based on the radiation dose information from the detection pixel group.
Claims9
A radiographic imaging apparatus comprising:
- a conversion unit configured to, in response to emission of radiation, convert the radiation to an electrical signal;
- a drive unit configured to drive the conversion unit;
- a readout unit configured to read out the electrical signal converted by the conversion unit;
- an image generating unit configured to generate an image based on the electrical signal read out by the readout unit;
- a determination unit configured to determine whether to stop the emission of the radiation;
- and
- a control unit configured to control operations of the drive unit, the readout unit, and the image generating unit,
- wherein the conversion unit includes a detection element configured to detect a radiation dose,
- wherein the determination unit determines whether to stop the emission of the radiation in response to the electrical signal converted by the detection element, and
- wherein the control unit controls termination of the operations of the drive unit, the readout unit, and the image generating unit based on a determination result of the determination unit.
