Medical imaging apparatus and control method for the same

One side is a substance by displaying, after re-projecting (reprojection) a separate and remove a volume of three-dimensional volume of the reconstructed object for each material constituting an object in a plurality of time by fusing them with the three-dimensional display device of the disclosed invention It provides the discrimination between, the contrast of the image is also enhanced three-dimensional and three-dimensional medical imaging device, and a control method. Medical imaging device according to an aspect of the disclosed invention is scanning unit for acquiring projection data for the target object; From the projected three-dimensional data restoration unit to restore the volume of the target object; Separate volume portions to separate the plurality of the material volume that correspond to the plurality of materials contained in the target object from the volume of the target object; Re-projecting the plurality of material volume in the plurality of virtual point portion reprojection for generating a plurality of re-projected images by the material; And an image fusing unit for generating a fusion image by the virtual viewpoint to fuse the material of the projection image in the same virtual point of a plurality of re-projected images by the material.
