Abstract
In this paper the well-established minimal path framework is applied to the problem of computing blood flow trajectories in phase contrast magnetic resonance imaging (PC-MRI). The velocity vectors measured by PC-MRI and an uncertainty measure are combined to a metric tensor and minimal paths are calculated with anisotropic fast marching method (FMM). Exemplary results of the computation of the blood particle trajectories are given. This work contributes a novel application of anisotropic FMM to flow computations.
