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.

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.

摘要： An inputting/designating section inputs a multimedia object or designates a multimedia object previously stored in a database. A feature-value-determining section determines the feature value of the input or designated multimedia object. A weighting-factor-determining section determines the determined feature-value weighting factor of the multimedia object. A similarity-retrieval section retrieves the similarity of the multimedia object previously stored in the database by using the determined feature value and the determined feature-value weighting factor. A displaying section displays a multimedia object similar to the multimedia object designated by the inputting/designating section in accordance with the result of similarity retrieval. A similarity-ranking-changing section changes similarity rankings of the displayed multimedia object. A similarity-recalculating section recalculates the feature-value weighting factor of the multimedia object in accordance with the changed similarity ranking and recalculates a similarity by using the feature-value weighting factor.

摘要： An object retrieval method used is characterized as follows. When a user selects objects, the dispersion between the objects is found with respect to each of a plurality of feature quantities. Within a retrieval range of objects, the dispersion between the objects is found with respect to each of a plurality of feature quantities. Both dispersions are compared for each feature quantity. As a result of the comparison, there may be a feature quantity which causes more converged dispersion in the selected objects. This feature quantity is provided with a weight larger than any other feature quantities to weight each feature quantity. An object is retrieved from the retrieval range based on the weighted feature quantities.
摘要翻译：使用的对象检索方法的特征如下。当用户选择对象时，针对多个特征量中的每一个找到对象之间的色散。在对象的检索范围内，相对于多个特征量中的每一个找到对象之间的色散。对每个特征量比较两个分散体。作为比较的结果，可能存在在所选择的对象中导致更多收敛的色散的特征量。该特征量具有比任何其他特征量更大的权重以对每个特征量进行加权。基于加权特征量从检索范围检索对象。
