Abstract: A storage unit stores at least one first analysis result generated by performing at least one first analysis process on an image of a subject and recovery information enabling recovery of a first analysis state where the first analysis result is generated or link information to the recovery information in a database in association with subject information specifying the subject. An analysis unit generates, in a case where at least one second analysis process generating at least one second analysis result different from the first analysis result is performed, the second analysis result by performing the second analysis process using the recovery information. The storage unit stores the second analysis result in the database in association with the subject information.

Abstract: A projection image of a three dimensional image is generated and displayed and a three dimensional target point corresponding to a designated two-dimensional target point is set to the three dimensional image. A reference cross-section is set to the three dimensional image by using the three dimensional target point. A cross-sectional two-dimensional image of the reference cross-section in which an object close to a point of view that faces the reference cross-section is not displayed is generated. An instruction to change the position of the point of view, using the three dimensional target point based on the cross-sectional two-dimensional image as a reference point, in order to align an observation direction of a structure to which the three dimensional target point is set with a target three dimensional direction is received. A new reference cross-section is set. A new cross-sectional two-dimensional image of the new reference cross-section is generated.

Abstract: A projection image is generated from a three-dimensional image by projecting an observation target in a predetermined projection direction. The generated projection image is displayed at a center of a display screen of a display device. A region extending in the predetermined projection direction from a central part of the display screen is set as set region, and at least a part of an overlapped region between the set region, which has been set, and the observation target is determined, as rotation center candidate region. Center of rotation is determined in the determined rotation center candidate region or in the vicinity thereof.

Abstract: A morphology image representing the morphology of a specific organ including a tubular structure in the inside thereof and a function image representing a function level at each position in the organ are obtained. A structure region representing a structure dominating the organ is extracted from the morphology image. A specific partial region in the extracted structure region and a dominated region in the organ are determined, and the dominated region being dominated by a structure in the partial region. In that case, at least one of the partial region determination step and the dominated region determination step is performed by using the function image.

Abstract: A structure extracting unit extracts a structure from a three-dimensional medical image, and a view point determining unit determines a view point position and a direction of line of sight of a virtual endoscopic image. An image generating unit calculates a distance between a view point position and the extracted structure, determines a display attribute of the extracted structure based on the distance and a plurality of different display attributes that correspond to different distances from the view point position and are defined for each of the structures, and generates, from the three-dimensional medical image, a virtual endoscopic image containing the structure having the determined display attribute. A display control unit displays the thus generated virtual endoscopic image on a WS display.

Abstract: A core-line extraction unit extracts a core line of the blood vessel from a three-dimensional image of a subject including the blood vessel. A local-route extraction unit extracts a local route of the core line within a predetermined range based on a reference point on the core line. In a case where a plurality of points on the local route are projected, a plane setting unit sets a plane having an orientation in which a distribution of a plurality of the projected points has a reference value based on a maximum value of the distribution, as a display plane of the three-dimensional image.
