Estimation of Guidewire Inclination Angle for 3D Reconstruction
Reconstruction of the 3D position of the guidewire is an important step toward automated navigation systems supporting minimally invasive endovascular interventions. We present a method to estimate the projected guidewire thickness for the monoplane X-ray configuration and we propose a novel method to recover the local angle between the guidewire and the X-ray path and to recover the inclination angle of the guidewire to the imaging plane, up to an orientation. We experimentally show the feasibility of the proposed approach by recovering both the local and the inclination angle of the guidewire ; the average error for the recovered inclination angle is 8.6+-8.2°.
