“…1 One method of assessing treatment-related uncertainties is via dosimetric intercomparison. 2,3 Level III studies, where measurement is made away from reference conditions in phantoms that mimic generic patients, [3][4][5][6][7] are frequently aimed at assessing the relationship between planned and delivered dose distributions, examining the general influence of local irradiation technique, inhomogeneity correction, etc.…”

“…These audits have improved the practice and accuracy of dosimetry in a wide range of RT centers and have helped in maintaining these levels over time 6 . Over the years the audits have evolved from mailed thermoluminescent dosimetry (TLD) measurements under reference conditions to nonreference conditions 55 and then to on-site end-to-end tests 56 . These audits have been found so useful that the IAEA, in its report on Accuracy Requirements and Uncertainties in Radiotherapy 6 made the recommendation that "An independent dosimetry audit should be performed for every new installation that is about to embark on radiation treatments.…”

The last few years have seen a significant growth of interest in the global radiation therapy crisis.Various organizations have quantified the need and are providing aid in support of addressing the shortfalls existing in many low-to-middle income countries (LMICs). With the tremendous demand for new facilities, equipment and personnel, it is very important to recognize the quality and safety challenges and to address them directly. An examination of publications on quality and safety in radiation therapy indicates a consistency in a number of the recommendations; however, these authoritative reports were generally based on input from high-resourced contexts.Here we review these recommendations with a special emphasis on issues that are significant in LMICs. While multidimensional, training and staffing are top priorities; any support provided to lower resourced settings must address the numerous facets associated with quality and safety indicators. Strong partnerships between high-income and other countries will enhance the development of safe and resource-appropriate strategies for advancing the radiation treatment process. The real challenge is the engagement of a strong spirit of cooperation, collaboration and communication between the multiple organizations in support of reducing the cancer divide and improving the provision of safe and effective radiation therapy.

“…6 An alternative structure with four levels has also been defined by the IAEA, as summarized by Izewska et al 7 A Level III study as discussed here would correspond to a Level 4 study according to the definitions of the IAEA. The advantage of a Level III dosimetric intercomparison is that the entire treatment chain from the acquisition of diagnostic images to the treatment setup and delivery can be verified.…”

Summary The present paper describes the logistics of the 2004–2008 Australasian Level III Dosimetry Intercomparison. Dosimetric intercomparisons (or ‘audits’) can be used in radiotherapy to evaluate the accuracy and quality of radiation delivery. An intercomparison was undertaken in New Zealand and Australia to evaluate the feasibility and logistics of ongoing dosimetric intercomparisons that evaluate all steps in the radiotherapy treatment process, known as a ‘Level III’ intercomparison. The study commenced in 2002 with the establishment of a study team, definition of the study protocol, acquisition of appropriate equipment and recruitment of participating radiotherapy centres. Measurements were undertaken between October 2004 and March 2008, and included collation of data on time, costs and logistics of the study. Forty independent Australian and New Zealand radiotherapy centres agreed to participate. Measurement visits were made to 37 of these centres. Data is presented on the costs of the study and the level of support required. The study involved the participation of 16 staff at the study centre who invested over 4000 hours in the study, and of over 200 professionals at participating centres. Recommendations are provided for future phantom‐based intercomparisons. It is hoped that the present paper will be of benefit to any centres or groups contemplating similar activities by identifying the processes involved in establishing the study, the potential hazards and pitfalls, and expected resource requirements.
