There might be a situation where initial dose planning was performed with mask-based immobilization and CBCT-based stereotactic coordinates and partial treatment was also delivered, but the patient can no longer tolerate the mask or is very anxious, with too much movement leading to multiple CBCT scans. In this scenario it is possible to interrupt mask-based treatment. LGK 11 allows conversion of a partially delivered dose plan to a frame-based treatment plan. This remaining treatment can be delivered using frame-based immobilization. Similarly, if needed the frame-based treatment plan can be converted to mask-based treatment.
