摘要： Using first voxel data of a three-dimensional medical image obtained by photographing a subject, a functional image representing a function of a heart in at least one position is generated, and using a portion of second voxel data of a three-dimensional medical image obtained by photographing the subject corresponding to an area which includes a blood vessel along an outer myocardial wall of the heart, a morphological image depicting morphology of the blood vessel is generated. Then, the functional image and the morphological image are displayed in a superimposing manner such that at least one position of the heart in the functional image corresponds to at least one position of the heart in the morphological image.

摘要： A diagnostic index that indicates a condition of obesity of an abdominal area of a human body with improved reliability is provided. For slice images representing two or more cross-sections of an abdominal area of a subject, a ratio of a size of the subcutaneous fat region and the visceral fat region in the abdominal area to the abdominal area is calculated. Then, the ratio obtained for the subject is compared with a corresponding ratio obtained in advance for a human body model to acquire the diagnostic index indicating the condition of obesity of the subject.

摘要： A pseudo three dimensional image is generated, based on an aspect image and a mapping image generated from an original three dimensional image, using a volume rendering method. A mapping image that represents the functions of a subject is generated using first voxel data that constitute an original three dimensional medical image of the subject. An aspect image is generated using second voxel data that constitute an original three dimensional medical image of the subject. A position matching means causes positions within a heart represented by the mapping image to correspond to positions within a heart represented by the aspect image. An image generating means executes volume rendering based on degrees of opacity within the mapping image, to generate the pseudo three dimensional image.

摘要： From CT images having captured an abdomen, a two-dimensional characteristic space is assumed, in which X and Y axes indicate CT values of image data taken in first and second time phases different from each other. In this space, a two-dimensional histogram concerning respective pixels located at the same position in the two time phases is taken as a sample distribution of pixels. A two-variable distribution function is applied to this sample distribution, so as to estimate a matrix distribution of pixels corresponding to the whole liver region. According to this matrix distribution, a range of CT value of pixels corresponding to the liver region is estimated.

摘要： In an image processing method for generating a pseudo three-dimensional image by a volume rendering method in which a pixel value of each pixel on a projection plane on which a three-dimensional image illuminated by an arbitrary light source is projected is determined using a brightness value at each examination point, which is a point on the three-dimensional image sampled along each of a plurality of visual lines connecting an arbitrary viewpoint and each pixel on the projection plane, an illuminance level at each examination point is calculated based on an opacity level at each calculation point, which is a point on the three-dimensional image sampled along each of a plurality of light rays connecting the light source and each examination point, and the brightness value at each examination point is determined based on the calculated illuminance level.

摘要： Structures in the vicinity of a target point (point of interest) within a diagnostic image are enabled to be observed in detail from multiple directions. Overview images (8, 9) that represent the overview of a structure (e.g., the large intestine) are generated based on volume data, and displayed on the screen (5) of a display. Points within the overview images and points corresponding thereto in the volume data are set as target points. Target volumes that include the target points and line of sight vectors within the volume data having the target points as endpoints and a movable viewpoint as a starting point are set within the volume data. The directions of the line of sight vectors are changed, and the target volumes are projected onto projection planes perpendicular to the directions of the line of sight vectors to generate detailed images (11) that represent details of the structure in the vicinity of the target points . The detailed images (11) which are generated accompanying changes in the line of sight direction are displayed sequentially or alongside each other on the screen.

摘要： A position obtainment means obtains the positions of points in the heart of a subject that are present in at least two three-dimensional volume datasets in a group of three-dimensional volume datasets that have been obtained by imaging the heart of the subject at predetermined time intervals, the points anatomically corresponding to each other, and the at least two three-dimensional volume datasets having been obtained by imaging at different time from each other. A function information obtainment means obtains, based on each of the positions of the points in the heart, which have been obtained by the position obtainment means, function information representing the function of the heart at each point within a three-dimensional space. A display means displays, based on the function information, the motion function of the heart at each of the points in an image that has the shape of the heart of the subject.
