摘要： PROBLEM TO BE SOLVED: To form a three-dimensional image having the clear outline and surface of an object site and having a three-dimensional appearance.
SOLUTION: An image processing function in a 3D image formation section includes an internal processing section 262, a boundary processing section 264, and a voxel computing section 266. The internal processing section 262 executes a uniformization process to the inside of the object site in the volume data, and the boundary processing section 264 executes a gradation process to a boundary between the object side and the other sites in the volume data. The voxel computing section 266 executes a volume rendering process to the volume data treated with the uniformization process and the gradation process so as to form the image data of three-dimensional images expressing the object site three-dimensionally.

摘要： PROBLEM TO BE SOLVED: To solve a problem that arises when forming a three-dimensional image by rendering processing using a three-dimensional region of interest, wherein the problem is generation of a striped pattern on a three-dimensional image due to curves on a rendering start surface or a rendering final surface. SOLUTION: Sample points 306 are set on each ray (line of sight) 304 at predetermined intervals, and voxel calculation is carried out individually for the sample points. In a first embodiment (A), weighting processing corresponding to the distance r between a final voxel and a final surface 302 is applied to an echo value e n of the final voxel, and final voxel calculation is carried out under such a condition. In a second embodiment (B), a final voxel is set on the final surface, weighting processing corresponding to the distance r is applied to an echo value e n+ so as to weight the echo value with the distance r, and voxel calculation is carried out with respect to the final voxel. By doing so, level differences in intensity values in the direction of the row of the rays is alleviated or prevented. COPYRIGHT: (C)2011,JPO&INPIT

摘要： 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 distance α, 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.
