PROGETTAZIONE DI IMMOBILIZZATORI PAZIENTE SPECIFICI PER LA RADIOTERAPIA CON UN SOFTWARE DI MODELLAZIONE PARAMETRICA

In radiotherapy, customized immobilization devices are essential to ensure accurate patient positioning during treatment. However, traditional design methods are often time-consuming, inflexible, and rarely tailored to individual anatomical needs—especially for arms and legs, where no personalized solutions are currently available. This forces clinicians to rely on standardized systems that do not provide optimal stabilization.
This thesis presents an *automated workflow using nTopology software* to model *custom-made immobilizers*, offering a faster and more adaptable alternative to conventional approaches. Three types of immobilizers were developed: head-neck, arm, and leg. All feature *lightweight and durable structures*, using *Voronoi patterns* for material efficiency and comfort.
The *parametric workflow* allows easy model adjustments based on clinical needs, overcoming the limitations of traditional CAD tools. The results confirm that automated design can significantly reduce development time and improve device personalization.
