In Vivo Interactive Visualization Of Four-Dimensional Blood Flow Patterns
Realtime assessment of volumetric phase contrast MRI: We give an overview over a series of experiments to visualize and measure flow fields in the human vascular system with respect to their diagnostic capabilities. The experiments utilize a selection of GPU based sparse and dense flow visualization algorithms to provide opportunities for volumetric cardiovascular phase contrast magnetic resonance imaging (PC-MRI). To evaluate the results, several hearts of human subjects have been investigated and a flow phantom was built up to simulate artificial distinctive flow features. Our results demonstrate that we are able to provide an interactive tool for cardiovascular diagnostics with independent but free combinable visualizations.
