Hi,
you might want to have a look at:

Evaluation of automated brain MR image segmentation and volumetry methods.
Hum Brain Mapp. 2008 Jun 6. [Epub ahead of print]
We use BrainWeb simulated data sets to evaluate the influence of different image quality parameters on segmentation performance.
Best,

Subject: [SPM] noise simulation
Dear Friends
We need to simulate fMRI noise for a quality control study.
Does anyone know if there's any existing tools/packages can do that?
We need to simulate the following noise:
1. Head motion
2. Scanner noise (ideally we want to simulate noise from different
scanners)
3. Respirations
4. others
Thanks
