Insertion support system for specifying a location of interest as an arbitrary region and also appropriately setting a navigation leading to the specified region
First Claim
1. A multi-planar reformatted image generating apparatus comprising:
- a three-dimensional image data storing unit for obtaining three-dimensional image data of a subject obtained by reformatting, on the basis of image data of a plurality of cross-sectional images in a three-dimensional region of the subject, the plurality of cross-sectional image data, and storing the obtained three-dimensional image data;
a multi-planar reformatted image generating unit for generating at least one multi-planar reformatted image which is a two-dimensional image of the subject on the basis of image data of a three-dimensional region in the subject stored in the three-dimensional image data storing unit;
a luminal organ information extracting unit for extracting information concerning the shape of the three-dimensional region of a predetermined luminal organ, on the basis of the image data of the three-dimensional region in the subject stored in the three-dimensional image data storing unit;
an extracted luminal organ image superimposing unit for superimposing an extracted luminal organ image, in which a result of the luminal organ extraction obtained by the luminal organ information extracting unit is reflected, on a predetermined cross-sectional image in the at least one multi-planar reformatted image to correspond to the predetermined cross-sectional image in the multi-planar reformatted image; and
a route setting unit for setting a route for inserting an endoscope in a duct of the luminal organ, on a superimposed two-dimensional image wherein the extracted luminal organ image is superimposed on the multi-planar reformatted image.

Abstract
According to an insertion support system of the present invention, when a biopsy area is specified at a periphery of the bronchi, the barycenter of the biopsy area is extracted. A circle centering on the barycenter is determined as a search area. The search area is expanded until the bronchi are located within the search area. A point in the search area to which the bronchi first reach is determined as an end point. A first route choice connecting the end point and a start point is determined. If the first route choice has not been registered yet, the first route choice is registered as a first registered route. Accordingly, a location of interest can be specified as an arbitrary region, and navigation leading to the specified region is appropriately set.
