Hello,
At the moment POSSUM can simulate any pulse sequence that is using
gradient-echo (so this includes MP-RAGE, FLASH ...). It can not simulate
spin-echo-based sequences at the moment but this is something we will be
including in the future.
POSSUM is developed to be used both for MRI and FMRI and some of its
applications are in simulating motion artifacts (including spin-history
ot blurring), B0 inhomogeneities, eddy currents etc. More details about
POSSUM and MIDAS you can find in:
I Drobnjak, D Gavaghan, E Süli, J Pitt-Francis and M Jenkinson.

Magnetic Resonance in Medicine, 56(2), 364-380, August 2006.
Hope this helps,
Best
