volume rendered
volume rendering is a is a set of techniques used to display a 2D projection of a 3D discretely sampled data set, typically a 3D scalar field.
my question is in this sentence "Figure7shows volume rendered velocity magnitudes of the coronary arteries during moderate exercise."does it say that figure 7 shows the magnitude of velocity using that technique? i also don't know it means velocity of what ? velocity of flow ?

Answer

The answer to both of your questions is "yes".

The figure shows the velocity of blood flow, displayed using the described 3D to 2D projection.
