Abstract
A medical image generation apparatus includes: a three-dimensional image acquisition unit that acquires a three-dimensional image in which a space including a patient is captured; an imparting unit that imparts, to each of voxels constituting the three-dimensional image, a living-body likelihood coefficient indicating a likelihood of being a living-body region of the patient; an updating unit that updates a luminance value of the voxel in which the imparted living-body likelihood coefficient shows a given value, through predetermined processing; a virtual viewpoint setting unit that sets a virtual viewpoint for transforming the three-dimensional image into a two-dimensional radiation image; and a radiation image generation unit that calculates a luminance value of a pixel constituting the radiation image based on the luminance value of the voxel existing along a line connecting each of the corresponding pixels and the virtual viewpoint.
