The TomoTherapy platform is a helical radiation therapy delivery system that integrates a linear accelerator and CT technology. It delivers accurate high-quality helical fan-beam image-guided, intensity-modulated radiation therapy (IG-IMRT) from multiple 360-degree rotations around the patient as the treatment table moves. It enables accurate control of the radiation dose so it conforms precisely to the tumor and minimizes dose to healthy tissues. The TomoTherapy platf… WitrynaIl sistema di tomoterapia, che nasce appositamente per l’esecuzione della metodica IG – IMRT (Image Guided Intensity Modulated Radiation Therapy), è una piattaforma per sviluppi futuri ed è completamente differente dalla tecnologia della radioterapia convenzionale, che invece è stata adattata a queste nuove tecniche ed è oramai un …
