Reconstruction of the 3D position of the guidewire is an important step toward automated navigation systems supporting minimally invasive endovascular interven-tions. We present a method to estimate the projected guidewire thickness for the monoplane X-ray configuration and we pro-pose 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 orienta-tion. We experimentally show the feasibility of the proposed approach by recovering both the local and the inclination an-gle of the guidewire; the average error for the recovered incli-nation angle is 8.6±8.2
