Randomized self-controlled study comparing open-face vs. closed immobilization masks in fractionated cranial radiotherapy

Radiotherapy is an essential part in the management of primary and metastatic brain tumors. To ensure safe and reproducible delivery of radiotherapy, accurate patient positioning and immobilization is required. The standard-of-care immobilization for fractionated brain irradiation, as for head-and-neck cancer, is an individually made thermoplastic mask which is closed around the patient ’s face. Closed masks provide stability, accuracy and reproducibility of each treatment fraction [1,2,3]. The inter- and intrafraction accuracy described by setup and head motion uncertainties for intracranial radiotherapy are reportedly 2–3 mm [4] and ∼ 2 mm [2], respectively.
