Abstract:
Dosimetry audit is widely recognized being a very important component of quality management program in radiotherapy (RT). At an institutional level, the external dosimetry audit provides an independent verification of the local approaches thus supporting the safe implementation of new and complex RT techniques. The International Atomic Energy Agency (IAEA) has developed two methodologies for on-site ”end-to-end” audits [1, 2] simulating the essential parts of 3D-Conformal Radiation Therapy (3D-CRT) and Intensity Modulated Radiation Therapy (IMRT)/Volumetric Modulated Arc Therapy (VMAT) RT workflows. The anthropomorphic phantoms are treated following the pathway similar to that of the patient and the doses verified by independent auditors. Both methodologies were applied in different nationwide RT centers which helped to evaluate the implementation of these RT techniques in the clinical practice.
