Novel feature-based visualization of the unsteady blood flow in intracranial aneurysms with the help of proper orthogonal decomposition (POD).
Computerized Medical Imaging and Graphics(2019)
摘要
•Feature-based blood flow visualization is proposed for intracranial aneurysms.•The 4D flow is decomposed with the help of proper orthogonal decomposition (POD).•The flow features are extracted with the help of the POD velocity modes.•The two most dominant flow features are combined in hybrid visualizations.•The novel POD-based visualizations are illustrated for 4D PC-MRI and CFD.
