Abstract:
A surgical operation navigation apparatus, comprising:medical image storage section for storing three-dimensional information of a subject measured by medical image diagnosis apparatus; modification information storage section for modifying and storing three-dimensional information of the subject stored in the medical image storage section based on predicted modification of the subject; morphological shape measuring instrument for measuring a three-dimensional morphological shape of the subject; position/posture detecting section for detecting a subject and a position/posture of a surgical operation utensil that carries out observation of the subject; modified morphological shape selecting section for comparing a three-dimensional morphological shape of the subject measured by the morphological shape measuring instrument with three-dimensional information stored in the modification information storage section, thereby selecting and outputting three-dimensional information of the subject which is the most analogous to a morphological shape of the subject from the modification information storage section; data image generating section for generating data image from the selected, outputted three-dimensional information of the subject; and image superimposing section for superimposing the data image from the data image generating section and the image of the subject from the surgical operation utensil on each other, thereby outputting the superimposed image to an image display device.
