Project: Primary standards and traceable measurement methods for X-ray emitting electronic brachytherapy devices

Acronym PRISM-eBT (Reference Number: 18NRM02)
Duration 01/07/2019 - 30/06/2022
Project Topic Electronic brachytherapy (eBT) targets tumours using X-rays from close range and has potential advantages over conventional radiotherapies. However, the systems available tend to have unique calibration methods; mostly indirect and with uncertainties larger than clinically acceptable. This means that treatment plans aren’t easily adapted from one system to another, impeding progress other therapy in clinical practice. This project will deliver harmonised, simplified and traceable dosimetry for eBT detectors and measurement devices, by determining 3D dose distributions in water models. Four primary standards will be developed for absorbed doses from internal radiotherapy devices, new measurement methods will be developed, and guidance produced. The outcome will be a harmonised calibration service, capable of promotion to the profession, plus calibration standards for independent and traceable verification of dosimetry, for both novel systems and for quality assurance of existing equipment. Comparability, backed by the first ever standards, will improve clinical confidence and, since treatment costs are lower than for conventional radiotherapies, increased uptake could reduce costs for Europe’s health systems.
