Abstract
Over the past decade, the quality of magnetic resonance angiograms has risen substantially with their clinical utility being progressively demonstrated. This acceptance has created a need for tools with which to summarize and display the information available. We have used a model based segmentation technique to extract vascular morphology and local flow parameters from phase contrast magnetic resonance angiograms. A multiresolution data structure is used as the basis of recursive decision-making to identify regions of blood flow. The resulting data representation allows more efficient data handling in subsequent processing and visualisation, and is directly applicable to the creation of a connected graph model of vascular regions. We describe this flow feature extraction algorithm and demonstrate the utility of the results.
