3.5 Cine Cardiac Fast Low-Angle Shot with Parallel-Imaging Technique
Figure 3.17: An overview of a volumetric time-dependent velocity-encoded dataset.
The phase-contrast velocity encoded images contain one spacial direction component
each. This part describes one slice for one certain volume. One volume consists of
several of these slices, so the number of recorded images for one volume is given by the
four images which are required for one slice, times the number of slices itself. Since we
handle four dimensional data, there is even one volume per time step. Consequently
the final number of raw images results by #images = 4 · #slices · #timesteps.
