In this research, we work with neurosurgeons on the extraction of neurovasculature in 2D and 3D angiograms for surgery planning. We employ a wave-propagation technique that models pixels or voxels are modeled as a medium through which a simulated wave may propagate.The likelihood that a pixel or voxel belongs inside blood vessels is modeled as a reflective index of the medium. Hence, by simply hitting the vascular image with a wave, we can extract the entire vessel tree. The structure is determined by simply tracing the wave back from each distal point in the propagated wave along the normals of the wavefronts.
The figure shows a wave propagated through a typically noisy angiogram to extract the Right Carotid Artery.
