RayStation Product Usage: is a software system designed for treatment planning and analysis of radiation therapy. The treatment plans provide treatment unit set-up parameters and estimates of dose distributions expected during the proposed treatment, and may be used to administer treatments after review and approval by the intended user.

Reason: For the proton QA preparation module in RayStation 6 (including SP1 and SP2), if the snout position or gap is modified in the QA module, the dose in the QA module may be computed for a different setup than what is used for QA measurements. This could result in an incorrect dosage being provided to a patient.
