Abstract
BackgroundIntraoperative radiotherapy (IORT) using the INTRABEAM® system promises a flexible use regarding radiation protection compared to other approaches such as electron treatment or HDR brachytherapy with 192Ir or 60Co. In this study we compared dose rate measurements of breast- and Kypho-IORT with C-arm fluoroscopy which is needed to estimate radiation protection areas. Materials and MethodsC-arm fluoroscopy, breast- and Kypho-IORTs were performed using phantoms (silicon breast or bucket of water). Dose rates were measured at the phantom's surface, at 30cm, 100cm and 200cm distance. Those measurements were confirmed during 10 Kypho-IORT and 10 breast-IORT patient treatments. ResultsThe measured dose rates were in the same magnitude for all three paradigms and ranges from 20μSv/h during a simulated breast-IORT at two meter distance up to 64 mSv/h directly at the surface of a simulated Kypho-IORT. Those measurements result in a circle of controlled area (yearly doses >6 mSv) for each paradigm of about 4 m±2 m. Discussion/ ConclusionsAll three paradigms show comparable dose rates which implies that the radiation protection is straight forward and confirms the flexible use of the INTRABEAM® system.
