Hi Glenn,
we did an intra- and inter- rater reliability study with a somewhat older version that wasn't as automated as the current one is, and the numbers were pretty much right on, so we don't worry about it anymore.
cheers, Bruce

Hi,
We are having a small discussion at our lab regarding inter- and intra-rater reliability numbers for our scan workups. We have a number of lab technicians processing the scans, a situation which I suspect is common to many research groups. I can think of a number of steps in the processing stream where operator input could change surface thickness measures. Yet I can't recall ever seeing inter/intra-rater reliability measures in publications. Nor is it mentioned in the FS documentation, and I don't think it is presented at the FS courses. The people I have asked about it (two different labs) have all said something like "ignore it, nobody does it."
How are other people handling this issue?
