hi all

First, apologies for this post being at best obliquely related to AFNI. However, I can't think of where else one could find expertise in this particular matter.

We are interested in obtaining a vacuum pillow to minimize head motion, as we are performing single-subject presurgical scans and the patients (understandably) often exhibit high to unacceptable amounts of motion. Unfortunately, it's hard to figure out exactly what we need and where to get it from a simple google search.

So I was wondering if you good people would fill me in on what model you use, whether it helps a lot, whether participants tolerate it well, where you got it, how much it costs, etc. If this is judged to be too off-topic for the AFNI board then could you email me personally at

james dot keidel at manchester dot ac dot uk?

Thanks so much in advance.
