Claim 0:
1. A system for confirming placement of a biopsy tool in a target comprising:
a catheter configured to receive the biopsy tool and to be placed for guiding the biopsy tool to the target;
a navigation component configured to track a position of the catheter navigated into a luminal network during a navigation phase; and
a processor and one or more non-transitory storage devices having stored thereon instructions, which when executed by the processor, cause the processor to:
receive a first plurality of fluoroscopic images;
generate a first fluoroscopic three-dimensional (3D) reconstruction from the plurality of fluoroscopic images;
present a first slice of the first fluoroscopic 3D reconstruction depicting the catheter in relation to the target, wherein the target is visible in the slice of the first fluoroscopic 3D reconstruction;
receive a second plurality of fluoroscopic images;
generate a second fluoroscopic three-dimensional reconstruction from the second plurality of fluoroscopic images;
define a first range of images from which a second slice of the second fluoroscopic 3D reconstruction is selected, the first defined range of images corresponding to a first end portion of the second plurality of fluoroscopic images and including less than half but greater than one of the second plurality of fluoroscopic images;
present on a user interface an indicator marking each of a beginning and an end of the first defined range of images within the second plurality of fluoroscopic images;
present on a user interface the second slice of the second fluoroscopic 3D reconstruction depicting the catheter, the second slice selected from the first defined range of images;
receive via the user interface an indication of a location of a tip of the catheter in the second slice of the second fluoroscopic 3D reconstruction;
define a second range of images, the second defined range of images corresponding to a second, opposite end portion of the second plurality of fluoroscopic images and including less than half but greater than one of the second plurality of fluoroscopic images;
present on a user interface an indicator marking each of a beginning and an end of the second defined range of images within the second plurality of fluoroscopic images;
present on the user interface a third slice of the second fluoroscopic 3D reconstruction depicting a target location, the third slice selected from the second defined range of images;
receive via the user interface an indication of a location of the target in the third slice of the second fluoroscopic 3D reconstruction; and
update a relative position of the target and the catheter in a 3D model of the luminal network.
