Abstract
An X-ray detector according to embodiments is an X-ray detector of a direct conversion type in which a plurality of X-ray detection elements are arranged in a column direction and a channel direction and voltage is applied between anodes and cathodes. The X-ray detector includes processing circuitry. The processing circuitry performs control so as not to use, for generation of image data, data from the X-ray detection elements in end portions in one of the column direction and the channel direction of the X-ray detection elements, and so as to use, for generation of image data, data from the X-ray detection elements in other than the end portions.
Claims9
An X-ray detector of a direct conversion type in which a plurality of X-ray detection elements are arranged in a column direction and a channel direction and voltage is applied between anodes and cathodes, the X-ray detector comprising:
- processing circuitry configured to perform control so as not to use, for generation of image data, data from the X-ray detection elements in end portions in one of the column direction and the channel direction of the X-ray detection elements, and so as to use, for generation of image data, data from the X-ray detection elements in other than the end portions,
- wherein the processing circuitry is further configured to perform control so as to read data from the X-ray detection elements in the end portions and data from the X-ray detection elements in other than the end portions, and prevent the data read from the X-ray detection elements in the end portions from being used for the generation of the image data.
An X-ray detector of a direct conversion type in which a plurality of X-ray detection elements are arranged in a column direction and a channel direction and voltage is applied between anodes and cathodes, the X-ray detector comprising:
- processing circuitry configured to use, for generation of first image data, data from the X-ray detection elements in other than end portions in one of the column direction and the channel direction of the X-ray detection elements, and use, for correction of first image data, data from the X-ray detection elements in the end portions.
