3D Guide Wire Navigation from Single Plane Fluoroscopic Images in Abdominal Catheterizations

Nowadays, abdominal catheterizations are mainly guided by 2D fluoroscopic imaging from one view, which complicates this task due to missing depth information, vessel invisibility, and patient motion. We propose a new technique for 3D navigation of guide wires based on single-plane 2D fluoroscopic views and a previously extracted 3D model of the vasculature. In order to relate the guide wire, which is only visible in the fluoroscopic view, to the 3D vasculature, we comprise methods for 2D–3D registration, apparent breathing motion compensation, guide wire detection, and robust backprojection. With this 2D-to-3D transfer, the navigation can be performed from arbitrary viewing angles, disconnected from the static perspective view of the fluoroscopic sequence.
