The role of in vivo dosimetry

In recent years, numerous publications have shown the feasibility and usefulness of in vivo dosimetry as an essential tool of quality assurance programs in radiotherapy [ 1,3,6,11]. In the context of this meeting on high dose/high precision radiotherapy, the presentations and discussions on in vivo dosimetry centred on its value for investigating the quality of specific treatment techniques: accuracy and reproducibility in dose delivery, benchmark role of in vivo dosimetyy, frequency of in vivo measurements and action levels for corrective actions.
