Visulaization of blood flow

Does anybody have a suggestion for which technique to use for blending of fluid data? Even better does anybody know where to find thorough information about visualization of blood flow ultrasound data?

What kind of data do you have?
Pressures? Velocities? Density?

If you want to model fluid there are loads of ways to do it depending on what information you want to visualise.

If you’re not wanting to model the fluid (i.e. mathematically generate the fluid behaviour based on conditions etc.), you probably just want to represent your data as a particle system.

An adaptation may be to use a meta-balls model to simulate the volume of the fluid.
