A similar image retrieving means has a region of interest setting portion, a feature quantity calculation portion, a similarity calculation portion and an image selection portion. A part of the three-dimensional image of the retrieval object is set as a region of interest. The feature quantity calculation portion calculates the quantity of the region of interest. The similarity calculation portion calculates the similarity between the retrieval object and the three-dimensional image data stored in advance by comparing the feature quantity of the region of interest of the retrieval object which quantity is calculated with the feature quantity calculation means with the three-dimensional image data where the region of interest is set which is stored in advance in the image database, and the feature quantity of this region of interest is calculated. The image selection portion selects similar images in an order of decreasing similarity from the image database.

摘要:
A surgical operation navigation apparatus comprises a medical image storage section that stores three-dimensional information of a subject measured by a medical image diagnosis unit. A modification information storage section modifies and stores the three-dimensional information of the subject based on predicted modification of the subject. A morphological shape measuring instrument measures a three-dimensional morphological shape of the subject. A morphological shape information storage section compares a three-dimensional morphological shape of a subject with three-dimensional information, and selects and outputs three-dimensional information of the subject that is the most analogous to the morphological shape of the subject. A data image generating section generates data image from the selected, outputted three-dimensional information of the subject. An image superimposing section superimposes a data image from the data image generation section and an image of the subject from the surgical operation utensil, and outputs the superimposed image to an image display device.

A navigation apparatus comprises a navigation-related information generating section and a display section. The navigation-related information generating section measures the position and orientation of an object and a target in a three-dimensional space and generate navigation-related information to be used for navigating the object toward the target. The display section displays the navigation-related information generated by the navigation-related information generating section in any of different modes depending on the relationship of the position and orientation of the object and that of the target. A surgical operation image acquisition/display apparatus comprises an observation section, an image display section and a specifying section. The observation section includes a plurality of observation sections whose position and orientation is modifiable. The image display section is adapted to alternatively display any of the images obtained by the observation sections or synthetically combine and display the combined images. The specifying section specifies the image to be displayed to the image display section according to the position and orientation of the observation section.
摘要:
A medical operation simulator includes a three-dimensional image reconstruction section, an instrument-image forming section, and an approach data presenting section. The three-dimensional image reconstructing section processes data representing slice images, thereby generating three-dimensional image data. The three-dimensional image data is supplied to a display device. The instrument-image forming section forms an image of a medical instrument. The image moves in the same way that a medical instrument provided on an operation input device is manipulated by an operator. The instrument-image forming section supplies data representing the image of the instrument to the display device. The display device displays the image of the instrument together with a three-dimensional image represented by the three-dimensional image data generated by the three-dimensional image reconstructing means. The approach data presenting section converts data showing an approach of the medical instrument toward a region of interest into at least one of an aural sensation, visual sensation, pressure sensation and touch sensation, by performing approach data presentation processing, and then presents at least one of the aural sensation, visual sensation, pressure sensation and touch sensation.
