Temporal tracking of coronaries in multi-slice computed tomography.
A method is proposed that performs a temporal tracking of the coronaries in multi-slice computed tomography (MSCT) dynamic sequences. The process exploits geometric moments and a local cylindrical approximation of the vessel to estimate the local characteristics of the structure in each volume and estimate its displacement along the sequence. The research strategy is based on a region matching process to find the location of the point in the successive volumes. A spatial tracking is then applied to refine its location inside the vessel. Tests have been achieved on simulated and real displacements of coronary segments.
