Abstract
Stereotactic Body Radiotherapy (SBRT) in the lung is a challenging technique which
requires high quality clinical trials to answer the un-resolved clinical questions.
Quality assurance of these clinical trials not only ensures the safety of the treatment
of the participating patients but also minimises the variation in treatment, thus
allowing the lowest number of patient treatments to answer the trial question. This
review addresses the role of dosimetry audits in the quality assurance process and
considers what can be done to ensure the highest accuracy of dose calculation and
delivery and it’s assessment in multi-centre trials.
