Abstract
A medical image processing apparatus and a medical image processing method that can reduce the noise bias of a corrected image in which high absorber artifacts included in a reconstructed image are corrected. The medical image processing apparatus has an arithmetic unit for correcting high absorber artifacts. The arithmetic unit comprises: a projection data generating section that generates projection data corresponding to a high absorber area in a reconstructed image with high absorber artifacts; a noise image generating section that generates a noise image using the projection data; and a weighted combining section that makes a weighted combining of the noise image with a corrected image in which high absorber artifacts are corrected.
