✦ Synopsis

Abstract

Novel image processing and computer graphics techniques were developed to create three‐dimensional (3D) models of vasculature from magnetic resonance (MR) angiographic images of the head or neck. Region growing was used to produce a mask that isolated the vascular signal in the MR angiographic data. The masked images were subjected to gradient‐shaded volume rendering to create 3D views of the vasculature. The computer‐derived model of intracranial vasculature was then merged with a 3D model of brain parenchyma derived from a set of MR images. The combined display of vascular and gyral anatomy may be useful for neurosurgical planning.
