Hi Mike, these are all great tips and certainly could only be gained through experience and time in testing. Thank you for sharing.

We are about to treat our first patient this week and the physics team has been asked to provide tolerances for re-imaging. I have provided values based on what was achievable with an anthropomorphic phantom (0.5mm translations and 0.3 degree rotations), stating clearly that clinical tolerances should be loosen.

Would something like what Kileigh is usingĀ (1mm, 0.5 degree) be a realistic starting point? If you don’t mind me asking, what tolerances are you guys using and how does this compare to the tolerances you had when you first started?

Cheers
