PROBLEM TO BE SOLVED: To solve the problem wherein in the case of displaying tissue of an embryo or the like, tissue as an obstacle on this side of the tissue is also imaged together. SOLUTION: The size of opacity is corrected according to the distance from an operation start surface 40. A plurality of visual lines penetrate a region of interest 13, and on the respective visual lines, voxel operation is sequentially performed voxel by voxel from the operation start point to the inmost side. In that case, in the range defined by a distanceα, the correcting processing is applied to increase the opacity gradually from the operation start point, so that while imaging of the placenta 10 is avoided as much as possible, the surface of the embryo 12 can be displayed more clearly.
