Abstract
A radiation detector according to an embodiment of the disclosure includes a substrate, a plurality of pixels arranged on the substrate, the plurality of pixels each including a switching element and a photoelectric conversion element, a scintillator arranged to cover the photoelectric conversion element of each of the plurality of pixels, and a storage device configured to store inspection image data acquired by irradiating the plurality of pixels with visible light before forming the scintillator or a calibration parameter based on the inspection image data.
Claims14
A radiation detector comprising:
- a substrate;
- a plurality of pixels arranged on the substrate, the plurality of pixels each including a switching element and a photoelectric conversion element;
- a scintillator arranged to cover the photoelectric conversion element of each of the plurality of pixels;
- and
- a storage device configured to store inspection image data acquired by irradiating the plurality of pixels with visible light before forming the scintillator or a calibration parameter based on the inspection image data.
A method for manufacturing a radiation detector, comprising:
- forming a plurality of pixels each including a switching element and a photoelectric conversion element, on a substrate;
- irradiating the plurality of pixels with visible light to acquire inspection image data from the plurality of pixels;
- writing the inspection image data or a calibration parameter based on the inspection image data into a storage device;
- and
- mounting the storage device configured to store the inspection image data written therein, on the substrate.
An imaging method for acquiring a radiation image by using a radiation detector including
- a substrate,
- a plurality of pixels arranged on the substrate, the plurality of pixels each including a switching element and a photoelectric conversion element, and
- a scintillator arranged to cover the photoelectric conversion element of each of the plurality of pixels, and
- a storage device configured to store inspection image data previously acquired by irradiating the plurality of pixels with visible light, during manufacture of the radiation detector, or a calibration parameter based on the inspection image data,
- the imaging method comprising:
- reading the inspection image data or the calibration parameter from the storage device,
- irradiating the radiation detector with radiation through a subject to acquire image data of the subject;
- and
- calibrating image data of the subject by using the inspection image data or the calibration parameter to acquire the radiation image.
