Abstract

A medical image processing apparatus comprises an image information processor that generates image information for acquiring a superposed image having a three-dimensional image of a medical device over a three-dimensional image of a preoperative structure of an object to which the medical device is inserted, and outputs the image information of the superposed image to a display apparatus.

First claim

What is claimed is:

1. A medical image processing apparatus comprising:
an image information processor that generates image information for acquiring a superposed image having a three-dimensional image of a medical device over a three-dimensional image of a preoperative structure of an object to which the medical device is inserted, and outputs the image information on the superposed image,
wherein the image information processor generates a three-dimensional image of the preoperative structure by segmenting a plurality of preoperative two-dimensional tomograms, further wherein each of the two-dimensional tomograms has a marker as a coordinate reference, and
wherein the image information processor calculates a form and a position of the medical device from a curvature state of the medical device, a position where the medical device is mounted, and the marker and generates a three-dimensional image of the medical device in the superposed image.

2. The medical image processing apparatus according to claim 1 , further comprising:
a curvature deformation detection unit that detects a deformation of the medical device, wherein
the image information processor generates a change-of-form information on the medical device, wherein the change-of-form information is at least one information piece selected from change-of-angle information, change-of-tilt information, and change-of-pressure information detected by the curvature deformation detection unit.

3. The medical image processing apparatus according to claim 1 , wherein each of the two-dimensional tomograms has a wider area image than an image corresponding to the image information on the superposed image output by the image information processor and displayed by a display apparatus.

4. The medical image processing apparatus according to claim 1 , wherein the image information processor outputs the image information on the superposed image by transmitting the image information on the superposed image to a display apparatus by radio.

5. The medical image processing apparatus according to claim 2 , wherein the image information processor determines that the curvature deformation unit is in contact with an internal structure of the object from the change-of-form information, and outputs an instruction to retract the inserted medical device from the object.
