8 Commissioning of 4 –10 mm conical collimators with Novalis TX® using TRS 483 protocol

This study focuses on the acquisition of basic dosimetry data for the implementation of SRS using conical collimators in the TPS iPlan (BrainLab) with the main objective of minimiz ing the uncertainties about the dose delivery. The collimator output factors (OF) measurement is one of the most critical points for very small beams characterization.
