Abstract

A new method has been developed that, based on tracking a guide wire in monoplane fluoroscopic images, visualizes the approximate guide wire position in the 3D vasculature, that is obtained prior to the intervention with 3D rotational X-ray angiography (3DRA). The method consists of four stages: (i) tracking of the guide wire in 2D fluoroscopic imaging, (ii) projecting the guide wire from the 2D fluoroscopic image back into the 3DRA image to determine possible locations of the guide wire in 3D, (iii) determining the approximate guide wire location in the 3DRA image based on image features, and (iv) visualization of the vessel and guide wire location found. The method has been evaluated using a 3DRA image of a vascular phantom filled with contrast, and monoplane fluoroscopic images of the same phantom without contrast and with a guide wire inserted. Evaluation has been performed for different projection angles. Also, several feature images for finding the optimal guide wire position have been compared. Average localization errors for the guide wire and the guide wire tip are in the range of a few millimetres, which shows that 3D visualization of the guide wire with respect to the vasculature as a navigation tool in endovascular procedures is feasible.
