Visualize Arterial Fluid Flow

• Data supplied by Pearl Flath

• Convert original data toHDF5 format

• Create a SCIRun network ofmodules to compute andinterpret data

• Launch the SCIRun Viewermodule, a GUI (GraphicalUser Interface)

• Network makes possibleinteractive exploration ofscalar and vector flow fields
