End-to-end test failure: what we found
Our quarterly end-to-end test showed a 1.2 mm offset. The cause was a recalibrated imaging isocentre that had not been updated in one system. Sharing our root-cause checklist.

Teaching case (fictional): ten lesions, largest 14 mm, smallest 3 mm. Single-isocentre dynamic conformal arcs, total treatment time under 20 minutes. I'd like feedback on the low-dose spill between the two frontal lesions.
Teaching case (fictional): T9 lesion with minor epidural extension. How would you contour the CTV around the epidural part, and would you go for separation surgery first?
Teaching case (fictional): 12 cm³ AVM, eloquent location. We are considering volume staging over two sessions six months apart. Experiences with staging versus hypofractionation?
