Abstract

Biplane X-ray angiography is currently the gold standard for navigational guidance during percutaneous interventions in vascular structures; but it remains limited to 2D projections. In this study, we propose a novel graph-based voxel coloring method for 3D reconstruction of vascular structures from biplane X-ray angiography sequences. The reconstruction is obtained by using the random walks algorithm on a graph-based representation of a discretized visual hull, to obtain the probability of belonging to the vascular structure. A multi-scale scheme is introduced to reconstruct at a finer level, while being computationally efficient. The proposed method was validated using the XCAT motion simulator and on calibrated clinical data.
