Brief Summary

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This study aims at providing a quantitative evaluation of the accuracy of two different fixation systems, where one system is also evaluated with two different set-ups. The first approach will be based on the BrainLAB thermoplastic masque (the masque with (= standard fixation) and without a custom made bite-block), the second will use the BrianLAB relocatable frame with the bite- block and a home made fixation system.
Repositioning accuracy will be evaluated in a randomized manner patient-dependent and independent with the two fixation systems mentioned above.
The rationale is to determine the margins to define the planning target volume (PTV), it is necessary to know the set-up accuracy of the immobilization system. An overestimation of the PTV would lead to possible toxicity and an underestimation could lead to a geographical miss.
The main endpoint of this trial will be the accurate reproducibility of the fixation system evaluated by repeated CT scan.
