[MINC-users] mrisim for cardiac MRI simulation

[Thomas Mansi]

Hello Andrew,

Many thanks for your quick answer. We keep looking at the possibilities 
offered by mrisim and, as the same time, we will test POSSUM as you 
suggested. By reading the introduction to the software it seems they 
implement motion artefacts among other distortions, which is very 
interesting for our application!

Many thanks again for your help,
Regards

Thomas
