Optimized scoring of end-to-end dosimetry audits for passive motion management – A simulation study using the IROC thorax phantom

Respiratory motion management is a standard feature of modern radiation therapy (RT) to thoracic and abdominal treatment sites in developed countries [1 –3]. Recent survey data have indicated that passive motion management techniques (including both the internal target volume (ITV) [4] and mid-ventilation [5] approaches) are by far the most prevalently used, most likely due to the now widespread availability of respiratory-correlated planning CT ( 4DCT) [2,3]. Implementing passive motion management in lung stereotactic body radiation therapy (SBRT) in particular is supported by evidence gathered in randomized clinical trials mandating its use, for example, TROG13.01, as well as other large cohort studies [6–8].
