Conclusion:

A large majority of Swiss radiation oncology institutions participated in this study. Whereas the Dmax, GTV coverage, and the CI were similar for 70% of them, the observed variation in 30% of the centres indicated further room for standardization.

Purpose/Objective:

The development of radiotherapy technology in Romania during recent years made it possible for public and private cancer centers to adopt intensity-modulated radiation therapy / volumetric modulated arc therapy techniques (IMRT/VMAT). In light of the complexity of advanced radiotherapy techniques, the dosimetry audit is becoming more
