Conclusion:

The majority of IVD results were within ±10% of the expected dose for both treatment schedules, with higher noticed differences in the neck and oral cavity region. Higher non-uniformities, additional compensations, and occasional corrections in delivered MUs could explain the remaining dose variations. In particular, in the 3-fraction schedule, any intervention registered a higher magnitude given the lower number of fractions remaining. These results confirmed the implemented technique’s robustness and validity in delivering the prescribed dose under IVD monitoring. Nevertheless, this technique and associated IVD are strongly time-consuming. An ongoing study focuses on possibly adopting a new efficient TBI technique exploiting IMRT and a different positioning method.
