Aorta Segmentation in Axial Cardiac Cine MRI via Graphical Models
We propose an automatic approach to aorta segmentation in axial cardiac cine MRI. The segmentation task is formulated as a probabilistic inference problem, seeking for the most pro...

Evaluation of Time-Dependent Wall Shear Stress Visualizations for Cerebral Aneurysms
For the rupture risk assessment of cerebral aneurysms, the blood flow is approximated using computational fluid dynamics (CFD). Unsteady CFD inflow conditions yield time-depende...

Enhancing Visibility of Blood Flow in Volume Rendered Cardiac 4D PC-MRI Data
Abstract. Four-dimensional phase-contrast magnetic resonance imaging (4D PC-MRI ) is a method to non-invasively acquire blood flow in the aorta. This flow is commonly visualized ...
