PROBLEM TO BE SOLVED: To make a simulation navigation system well match with an actual case. SOLUTION: The phantom has an outer container 1 of a skull model corresponding to the outside surface of the head of the examinee, a soft molding 2 corresponding to a concern section and a soft packing body 2 corresponding to the intermediate content of the examinee. Since there is a difference in the material quality so as to allow the discrimination on an X-ray CT image for reference between the soft molding 2 and the soft packing body 4, the phantom internal structure can be exactly grasped form the X-ray CT image for reference with which the soft molding 2 and the soft packing body 4 are distinctly discriminated. In addition, since the inside of the outer container 1 consisting of the soft packing body 2 and the soft molding 4 are in the soft state resembling that in the human body, the feel of a surgical operation implement is made nearly the feel in the case of the actual human body, as a result a simulation navigation well corresponds to the case of the navigation at the time of the actual surgical operation can be carried out. |
