A novel approach to correct magnetic resonance phase contrast angiography (MR-PCA) based on the coupling computational fluid dynamics (CFD) to vessel segmentation in the level set methodology. MR-PCA data is supplied not only to partial differential equation based fast local level set vessel segmentation as the initial condition, but also to CFD code using level set ghost fluid method as the initial and boundary conditions. These procedures are integrated to provide with the corrected velocity field in the most optimal vessel geometry. The application of this system to both synthetic and clinical data are shown and validity is discussed.
