FIG. 10.

Example of clinical cases. (A) Guidewire in aneurysm with additional objects in the image (stent, previous guidewire, leftover contrast medium, and registration artifacts). (1) Original fluoroscopy frame. (2) Binarized image overlaid with extracted line segments. (3) Extracted 2D path overlaid with original fluoroscopy image. (4) 3D reconstruction of the guidewire within the aneurysm. (B) Coiling of aneurysm. (1) Extracted 2D path after 1.5 loops. (2) 3D reconstruction after 1.5 loops. (3) After multiple loops, 2D path cannot be extracted correctly. (4) Failed 3D reconstruction after multiple loops.
