Abstract

Magnetic Resonance Angiography (MRA) is now an essential magnetic resonance imaging (MRI) pulse sequence technique especially for the diagnosis of intracranial vessel diseases. The intracranial vessels can be depicted by Maximum Intensity Projection (MIP). MIP projects the individual MRA slice and extracts the maximum intensity in a selected projection ray. However, the small intensity of vessels can be ignored in the projected plane. A 3D surface visualization scheme is proposed to encompass the small intensity of intracranial vessels by enhancing the intensity of vessels and integrating the Marching Cube Iso-surface algorithm into SGI Open Inventor framework. The Open Inventor framework's viewer provides the navigation utilities to depict the vessels vividly with an interactive frame rate.
