Endoscope system
First Claim
1. An endoscope system, comprising:
- a storage portion that stores image information for constructing three-dimensional image information relating to a subject that is previously acquired;
a luminal organ extraction portion that, by constructing the three-dimensional image information based on the image information, extracts a predetermined luminal organ that is present in the three-dimensional image information;
an image pickup portion that picks up an image of inside the subject;
a position information acquisition portion that acquires position information of the image pickup portion;
a position alignment portion that makes the position information acquired by the position information acquisition portion correspond to position information of three-dimensional image coordinates of the predetermined luminal organ; and
an image processing portion that generates trail information based on the position information of the image pickup portion, and based on a result of the position alignment portion, creates an image in which current distal end position information of the image pickup portion and determination information indicating a place that an image pickup portion distal end reaches inside the predetermined luminal organ and a place that the image pickup portion distal end has not reached, which are determined from the trail information, in different display forms are superimposed in a distinguishable manner on three-dimensional image information of the predetermined luminal organ.

Abstract
An endoscope system includes: an image processing portion that constructs three-dimensional data based on preoperative multi-slice image data and extracts a predetermined luminal organ; a position detection apparatus that acquires position information of an image pickup portion; a position alignment portion that makes position information of the image pickup portion correspond to coordinates of the three-dimensional data; and an image processing portion that generates trail information based on the position information of the image pickup portion, and based on a result of the position alignment portion, creates an image in which past trail information, insertion shape information including current distal end position information with respect to the image pickup portion, and determination information obtained by determining whether or not the image pickup portion passes through a duct in three-dimensional data of the predetermined luminal organ are superimposed in a distinguishable manner on three-dimensional image information of the predetermined luminal organ.

8. An endoscope system, comprising:
-
a storage portion that stores image information for constructing three-dimensional image information relating to a subject that is previously acquired; a luminal organ extraction portion that, by constructing the three-dimensional image information based on the image information, extracts a predetermined luminal organ that is present in the three-dimensional image information; an image pickup portion that picks up an image of inside the subject; a position information acquisition portion that acquires position information of the image pickup portion; a position alignment portion that, makes the position information acquired by the position information acquisition portion correspond to position information of three-dimensional image coordinates of the predetermined luminal organ; a determination portion that, based on a result of the position alignment portion, determines whether or not the image pickup portion passes through a duct in the predetermined luminal organ by setting a point that is nearest to centerline data of the predetermined luminal organ in the three-dimensional image information to be a trail point with respect to respective position coordinates of an image pickup portion distal end; and an image processing portion that, based on the result of the position alignment portion, generates trail information from the position information of the image pickup portion, and superimposes past trail information in the trail information on centerline data of a range in which the trail point exists, and creates an image in which insertion shape information including current distal end position information of the image pickup portion, and determination information which is obtained by determining whether or not the image pickup portion passes through a duct in the predetermined luminal organ are superimposed in a distinguishable manner on three-dimensional image information of the predetermined luminal organ.
