First Claim
Patent Images
1. An insertion support system comprising:
- virtual image generating unit for generating three-dimensional images of a duct in a body cavity in a subject as successive virtual images in frame units, on the basis of image data of a three-dimensional region in the subject;
navigation image generating unit for generating a navigation image including an endoscope configured to capture images of the duct in the body cavity in subject, the virtual image, and a plurality of reduced size images of the virtual image at all branch points at which the duct in the body cavity in the subject diverges;
rotation information storing unit for storing image rotation information of the reduced size images;
rotation amount comparing unit for comparing the image rotation information of the reduced size images and rotation angle data of the virtual image; and
image rotation controlling unit for rotating the reduced size images generated by the navigation image generating unit, on the basis of a result of the comparison made by the rotation amount comparing unit.
