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?
The 11th Novalis Circle Conference takes place in Munich from 20 to 22 May 2027. Submit your abstract for the clinical, physics or RTT track by 15 January 2027.
Congratulations to three more centres on completing Novalis Certification this quarter. Their teams share what they learned in the Novalis Certified Centres group.
Expert questions, cases, events and your clinical groups, on iPhone and Android. This is a preview of the new Novalis Circle app; tell us what you think.
Selected plenary talks, physics sessions and the poster walk from Conference 2026 are now in the video library.

When we started the certification process, we thought it was about QA documents. It turned out to change how our whole team works together. Here is what we learned in five years.

Teaching case (fictional): lower-lobe lesion moving 22 mm. We compared an internal target volume plan with a gated plan. The gated plan reduced the lung V20 considerably, at the cost of longer treatment.

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): recurrent pain two years after MVD. Targeting was harder because of postoperative changes. Imaging and targeting approach in the comments.
Our centre went from an empty bunker to our first radiosurgery patient in 18 months. Staffing, commissioning, training and the mentors who helped us along the way.
