A method and apparatus for three-dimensional (3D) vessel localization is presented to allow the identification of a vessel of interest, the selection of a vessel segment, and the determination of a slice orientation to improve the accuracy of phase-contrast magnetic resonance (PCMR) angiography. A marching-cube surface-rendering algorithm is used to reconstruct the 3D vasculature. Surface-rendering is obtained using an iso-surface value determined from a maximum intensity projection (MIP) image. This 3D vasculature is used to find a vessel of interest, select a vessel segment, and to determine the slice orientation perpendicular to the vessel axis. |
