1. A medical image processing apparatus which processes X-ray transmission data collected by an X-ray rotational photographing mechanism, comprising: a storage unit which stores a plurality of pieces of human anatomy figure image data collected by photographing a subject before the injection of a contrast media at a plurality of projection angles and a plurality of pieces of contrast image data collected by photographing the subject after the injection of the contrast media at the plurality of projection angles; a subtraction unit which subtracts the contrast image data from the human anatomy figure image data, which are pieces of image data having the same projection angle concerning the photography, to generate contrast blood vessel figure data; a first reconfiguration unit which executes reconfiguration processing based on the plurality of pieces of contrast blood vessel figure data generated by the subtraction unit to create contrast blood vessel figure three-dimensional image data; a second reconfiguration unit which executes reconfiguration processing based on the plurality of pieces of human anatomy figure data to generate human anatomy figure three-dimensional image data; a black-and-white reverse processing unit which executes black-and-white reverse processing with respect to the contrast blood vessel figure three-dimensional image data to generate non-blood-current figure three-dimensional image data; and a combination processing unit which combines the human anatomy figure three-dimensional image data with the non-blood-current figure three-dimensional image data to generate combined image data.
