Abstract: In a CPR image generation apparatus, method, and program, a CPR image is generated so as to include a region of interest, such as a branch, a myocardium, a plaque, and a lesion. A structure extraction unit 22 extracts a coronary artery region 30 from a three-dimensional image G0. A cross section setting unit 23 sets a cross section Pk perpendicular to a reference line L0 for each point on the reference line L0 in the coronary artery region 30. In a case where a region of interest is present on each cross section Pk, a cutting plane determination unit 24 determines one cutting plane Ck in each cross section including the reference line L0 and the region of interest. An image generation unit 25 generates a CPR image G10 including the cutting plane Ck.

Abstract: An initial position aligning unit performs initial positional alignment of a video and simulation data, and a position aligning unit performs positional alignment of the video and the simulation data. A first movement detecting unit detects movements of reference points which are set within a first image of the video, and a second movement detecting unit detects movement of a camera. A degree of reliability calculating unit compares the first and second movements to calculate a degree of reliability with respect to the movements of each of the reference points.

Abstract: For assigning a binary label representing belonging to a target region or not to each pixel in an image: a predicted shape of the target region is set; a pixel group including N pixels is selected, where N is a natural number of 4 or more, which have a positional relationship representing the predicted shape; and an energy function is set, which includes an N-th order term in which a variable is a label of each pixel of the pixel group, so that a value of the N-th order term is at a minimum value when a combination of the labels assigned to the pixels of the pixel group is a pattern matching the predicted shape, and increases in stages along with an increase in a number of pixels to which a label different from the pattern is assigned. The labeling is performed by minimizing the energy function.

Abstract: When a virtual-endoscopic-image is generated from a three-dimensional-image representing a tubular-organ, a predetermined range is set in the vicinity of a viewpoint set in advance in the three-dimensional-image, and each of a lumen-region and a wall-region of the tubular-organ in the set range is identified. A voxel-value or a voxel-value-interval constituting a boundary between a range of voxel values in the identified lumen-region and a range of voxel values in the identified wall-region is obtained based on information about voxel-values in the identified lumen-region and information about voxel-values in the identified wall-region, and an opacity-curve representing a relationship between voxel values and opacity is set in such a manner that the opacity changes from a value representing a transparent-state to a value representing an opaque-state at the voxel-value or in the voxel-value-interval. The virtual-endoscopic-image is generated from the three-dimensional-image by volume rendering using the set viewpoint and the set opacity-curve.
