摘要:
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 reference frame adapted to be fitted to a subject of medical treatment and provided with markers for determining the position or the orientation of the subject comprises fitting section for fitting the reference frame with the subject at least three spots (tops of the left and right ears and the nasal projection) along the undulations of the surface thereof and three or more than three markers detectable at least ether in an X-ray image or in an MRI image of the reference frame, the markers being to be arranged at predetermined positions not connectable by a straight line. A surgical operation navigating system determines the coordinates of the markers in a coordinate system defined for the image taken for the purpose of medical examination of the subject who is carrying the reference frame on the basis of the obtained image. Then the corresponding relationship is established between the coordinate system for the image for examination and the coordinate system for the real space containing the markers on the basis of the result of the operation of determining the coordinates of the markers in the coordinate system for the image for examination and the coordinates of the markers in the coordinate system for the real space.

A feature quantity calculation device to calculate a feature quantity for a 3-D object from 3-D object data contained in the 3-D object includes a 3-D object data input module to input the 3-D object data, a 3-D object data analysis module to analyze the input 3-D object data, a volume data conversion module to convert the analyzed 3-D object data to volume data, and a feature quantity calculation module to calculate a feature quantity from the converted volume data.
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.
摘要:
The present invention writes the obtained two-dimensional image data of a body including a diseased portion in a computer or the like, and displays a three-dimensional image of the body including the diseased portion and the related data in the same monitor. The diseased portion data is then converted into a three-dimensional construction with use of a three-dimensional construction reconstructing section. The geometrical center of the three-dimensional constructed image is calculated by a geometrical center calculation section, and a plurality of linear lines or one linear line having the shortest distance directing from the geometrical center to the outside of the body is then calculated. The calculated line/lines is/are displayed to be overlapped on an image of the body including the diseased portion. In this manner, the present invention provides a stereotaxy operation route searching apparatus for showing a guideline of a low-invasive operation strategy to an operator, and the searching method.

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.

An information presentation system includes an imaging unit, a peripheral information acquisition unit which acquires peripheral information, a storage unit which stores registered information, an analytic basic information construction unit which constructs analytic basic information from the registered information stored in the storage unit, on the basis of the peripheral information acquired in the peripheral information acquisition unit, a pertinent information acquisition unit which acquires information pertinent to the image from the image obtained from the imaging unit and the analytic basic information obtained from the analytic basic information construction unit, and a presentation unit which presents the pertinent information acquired in the pertinent information acquisition unit. The analytic basic information construction unit changes the analytic basic information on the basis of at least one of a time, date, season, weather, temperature, humidity, place, surrounding brightness, average color/color distribution of the acquired image, surrounding sound and model.
