Abstract:
External dosimetry audit is a tool for quality improvement in radiotherapy (RT), being widely recognised to ensure patient dosimetry accuracy and consistency. Large scale audits have provided data which helped to increase the confidence in dose delivey and allowed RT institutions to benchmark themselves against others with similar equipment and thus find out if they have got the best out of a system [1]. In order to review the physics aspects of the overall clinical Intensity Modulated Radiation Therapy (IMRT) performance, a multi-institutional pilot study was carried out in five RT institutions nationwide, with six medical linear accelerators being involved. The International Atomic Energy Agency (IAEA) "end-to-end" audit methodology for on-site verification of IMRT dose delivery, which simulates all the steps of an IMRT treatment, in an ‘end-to-end’ approach (i.e., following the pathway similar to that of the patient, from imaging, through treatment planning to the dose delivery) using an anthropomorphic CIRS Shoulder, Head&Neck End-to-End (SHANE) phantom was followed [2]. Overall, the multi-institutional pilot study results showed that an accurate treatment delivery, within the recommended agreement criteria, is achieved in the centers, thus showing a high quality of IMRT/volumetric modulated arc therapy (VMAT) clinical implementation for Head&Neck treatments.
