NAVIGATION SYSTEM AND OPERATION METHOD OF NAVIGATION SYSTEM

摘要

A navigation system includes an alignment unit configured to generate corrected position information in which position information of a viewpoint of an endoscope that is inserted in a subject is aligned with a three-dimensional image of a luminal organ, a determination unit configured to determine performance/non-performance of observation of a branch conduit based on the corrected position information, a target setting unit configured to set one unobserved conduit as a first target region based on a distance between the position information of the current viewpoint and the unobserved conduit, and a navigation information generation unit configured to generate navigation information for the first target region.

1. A navigation system comprising:
a position information acquisition unit configured to acquire position information of a viewpoint of an endoscope that is inserted in a subject; an alignment unit configured to generate corrected position information in which the position information of the viewpoint acquired by the position information acquisition unit is aligned with a three-dimensional image of a predetermined luminal organ in the subject; a determination unit configured to determine, with respect to a plurality of branch conduits in the predetermined luminal organ, whether each of the plurality of branch conduits is already observed or is still unobserved by the endoscope, based on the corrected position information; a target setting unit configured to set, when a branch conduit determined by the determination unit as unobserved is given as an unobserved conduit, one unobserved conduit as a first target region, based on a distance between the position information of the viewpoint at a current time acquired by the position information acquisition unit and the unobserved conduit; and a navigation information generation unit configured to generate navigation information for the first target region set by the target setting unit.
