摘要
An X-ray computed tomography apparatus (100) according to the embodiment is characterized by including an X-ray generation unit (105) generating X-rays, an X-ray detection unit (3) detecting X-rays generated from the X-ray generation unit (105) and transmitted through an object, a projection data generation unit (300) generating projection data based on an output from the X-ray detection unit (3), a variance data generation unit (400) generating variance data based on the projection data and noise data concerning predetermined noise, a statistical weight generation unit (500) generating a statistical weight by compressing the variance data to a predetermined data range, and a reconstruction unit (700) reconstructing volume data by iterative reconstruction processing based on the projection data and the statistical weight.
