Description
A strong homogeneous magnetic field which
cause a small total magnetization of a spinsystem.
The order of magnitude is about
0.5...3[T esla] for clinical usage and up to
7[T esla] in experimental setups.
Velocity ENCoding value. A reference velocity
value which has to be determined in advance
for flow-sensitive PC-MRA to acquire a
correct mapping from the phase angle of moving
spins to the range of values.
In contrast to a 2D texture with coordinates
u, v a three dimensional texture consists of n-
2D textures providing a third index w. Modern
graphics hardware support these types of
texture. Their Visualization is not trivial and
many approaches to that issue exist.
