X-ray detection device and detection method

Abstract

The present disclosure relates to an X-ray detection device and a detection method, which can improve a sampling rate and spatial resolution without increasing an exposure dose to a subject. The X-ray detection device according to an aspect of the present disclosure includes: a scintillator adapted to generate scintillation light in response to incident X-rays; a detection unit including a plurality of pixels each generating a pixel signal in response to the scintillation light incident thereon; and an output unit adapted to generate the X-ray two-dimensional projection data by using the pixel signals of the pixels, in which the pixel of the detection unit includes: a plurality of subpixels adapted to perform photoelectric conversion in response to the scintillation light; an AD conversion unit adapted to apply AD conversion to outputs of the subpixels; and an adder adapted to generate the pixel signal corresponding to the pixel by adding up outputs of the plurality of subpixels after the AD conversion. The present disclosure is applicable to an X-ray CT device and an X-ray FPD device.
