We present a fully automatic post-processing method for 3D time-of-flight MR Angiograms. The method produces maximum intensity projections of pre-specified regions of interest that are warped to a patient using the non-rigid deformation field obtained from registration. We evaluated the method using a three-point Likert scale to proof that it performs at least as good as the current manual clinical method.
