Abstract
Provided are an X-ray CT apparatus and a tomographic image generation method capable of reducing a difference in a sum of weights for each projection angle in a tomographic image. There is provided an X-ray CT apparatus including: a projection data acquisition unit configured to acquire projection data of a subject; a reconstruction weight calculation unit configured to calculate a reconstruction weight based on the projection data; and an image generation unit configured to generate a tomographic image while weighting the projection data with the reconstruction weight, in which the reconstruction weight calculation unit is configured to calculate a reconstruction weight, which includes a reliability weight indicating a degree of reliability of the projection data, through standardization using a sum of weight coefficients obtained for each projection angle.
