Hi,
Here's a suggestion for the imaging task [1]: an MRI simulator.
mrisim is a simple MRI simulation program which produces MINC
volumes from a segmented and labelled brain phantom. It allows
intrinsic tissue parameters (T1, T2...) and pulse sequence
parameters (TR, TE ...) to be specified and then produces simulated
images with noise. Currently, no artifacts are implemented.
