Object-Centered Description for Analysis and Display of the Cerebral Vascularity

T. Koller, G. Gerig and G. Székely
CAR'95 Computer Assisted Radiology
June 1995


This paper present a new prototypical system for the comprehensive analysis of the cerebral vascularity. The geometrical shape and the topology of the vessel tree is segmented from MRA volume data and is fused with additional information about local blood flow. Interactive manipulation tools make use of this rich model and of the object-oriented data structure, providing an interactive display of vascularity which goes by far beyond a simple 3-D rendering. Several case studies demonstrate the potential usage for structure identification, definition of landmarks, assessment of topology for catheterization, visualization of blood flow and simulation of bolus injection.
