Using AlignRT, we can monitor the patient at every couch angle. At our institution we evaluated the accuracy of our AlignRT system at non-coplanar couch angles and saw submillimeter accuracy (in the order of 0.3mm). With that knowledge we are comfortable treating with non-coplanar angles and monitor the patient using SGRT.

When training staff on new technologies or workflows we always circle back to see if there is anything we need to improve on. After a few weeks of hands on learning we usually gather and talk about the workflow and if we feel we need more training or experience before moving to the next step or level. Only once we "mastered" a workflow we are ready to move to the next. In the context of SGRT, we started with a breast workflow, moved to DIBH, then explored other body sites until we were at every patient, every fraction.
