QA networks for radiotherapy dosimetry
نویسنده
چکیده
Several national and international organizations have developed various types and levels of external audits for radiotherapy dosimetry, either based on on-site review visits or using mailed dosimetry systems. Three major TLD (thermoluminescent dosimetry) networks make available postal dose audits to a large number of radiotherapy centres on a regular basis. These are the IAEA/WHO TLD postal dose audit service operating worldwide; the European Society for Therapeutic Radiology and Oncology (ESTRO) network known as EQUAL operating in the European Union (EU); and the Radiological Physics Center (RPC) in North America. Other external audit programmes are either associated with national and international clinical trial groups, or perform national dosimetry intercomparisons checking radiotherapy dosimetry at various levels. This paper discusses the present status of the worldwide QA networks in radiotherapy dosimetry and reviews the activities of three main TLD networks: the IAEA/WHO, the EQUAL and RPC networks.

Dosimetry for audit and clinical trials: challenges and requirements
Many important dosimetry audit networks for radiotherapy have their roots in clinical trial quality assurance (QA). In both scenarios it is essential to test two issues: does the treatment plan conform with the clinical requirements and is the plan a reasonable representation of what is actually delivered to a patient throughout their course of treatment. Part of a sound quality program would b...
