HDR brachytherapy postal audit across Australia and New Zealand with in air jig
摘要
Dosimetry audits are a key component of radiotherapy quality improvement, however lack of appropriate tools and resources may be hampering the adoption of audit practices for brachytherapy in particular. In this study, an audit method was developed around a 3D printed reference air kerma rate (RAKR) measurement jig and a pilot high dose rate (HDR) postal audit was completed across eighteen HDR centres across Australia and New Zealand. This pilot study allowed the performance of the 3D printed jig and accompanying audit spreadsheet to be assessed, to inform the design of future iterations of the 3D printed jig tool and provide baseline data for future brachytherapy audits.
