摘要： Overview images that represent the overview of a structure (e.g., the large intestine) are generated based on volume data, and displayed on a screen. Points within the overview images and points corresponding thereto in the volume data are set as target points. A target volume that includes 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 by moving the viewpoint, and the target volumes are projected onto projection planes perpendicular to the directions of the line of sight vectors to generate detailed images that represent details of the structure in the vicinity of the target points. The detailed images are displayed on the screen.

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： 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.
