Hi Joanne
I would be cautious with the statement that AOC will fix the errors seen under couch rotation. This only holds true when you have a perfect mechanical couch behaviour under rotation and as we know this is seldom the case. So before you make judgments on the accuracy of the RTDs under rotation you must acquire knowledge on your mechanical couch runout under rotation by other means than AlignRT. By saying that I don’t question that AOC will improve accuracy.
Best regards
Daniel
