Abstract:
A system and method for enhanced navigation for use during a surgical procedure including planning a navigation path to a target using a first data set of computed tomography images previously acquired; navigating a marker placement device to the target using the navigation path; placing a plurality of markers in tissue proximate the target; acquiring a second data set of computed tomography images including the plurality of markers; planning a second navigation path to a second target using the second data set of computed tomography images; navigating a medical instrument to a second target; capturing fluoroscopic data of tissue proximate the target; and registering the fluoroscopic data to the second data set of computed tomography images based on marker position and orientation within the real-time fluoroscopic data and the second data set of computed tomography images.

Claim (Index 21):
A method for enhanced surgical navigation comprising:\n planning a navigation path using a first data set of computed tomography images of a branched luminal network previously acquired, the navigation path defining a route to be followed through the branched luminal network to a target; displaying the route of the navigation path on a graphical user interface for a first navigation to the target by following the route and for placement of a plurality of markers in tissue proximate the target; navigating a marker placement device to the target by following the route of the navigation path; placing a plurality of markers in tissue proximate the target using the marker placement device; acquiring a second data set of computed tomography images of the branched luminal network including the plurality of markers; generating a three-dimensional model of the branched luminal network from the second data set of computed tomography images; planning a second navigation path through the branched luminal network using the three-dimensional model generated, the second navigation path defining a second route to be followed through the branched luminal network to the target for a second navigation to the target; navigating a medical instrument to the second target by following the second route of the second navigation path; capturing fluoroscopic data of tissue proximate the plurality of markers; registering the fluoroscopic data to the second data set of computed tomography images; and creating a composite fluoroscopic image including the fluoroscopic data and an object visible in the second data set of computed tomography images that is not clearly visible in the fluoroscopic data.
