Código de referência IPL/2016/SoftImob_ISELAn effective head immobilization is an important requirement in radiotherapy treatment sessions, although it may also be thought in the future as a precious aid in brain medical imaging. Thus, the present work is focused on the stiffness optimization of a customized head immobilization mask, modelled upon the head reconstruction surface based on computerized tomography images. This paper proposes a strategy supported by a metaheuristic optimization technique and a metamodeling approach for the whole mask, illustrated at its most unfavorable region occurring in the gnathion region.engRadiotherapyBrain cancerBiomechanicsComputerised tomographyElasticityImage reconstructionMedical image processingCustomized head immobilization maskMetamodeling approachGnathion regionconference object
