"Verification of Gynaecological Brachytherapy Treatments Using an End-t" by Yashiv Dookie

High dose rate brachytherapy allows the delivery of radiation internally, with high-dose gradients creating a conformal distribution. The inherent drawback of this treatment exists within small uncertainties producing a large impact on safety and efficacy. Applicator displacement was ret-rospectively simulated for 29 cervical cancer treatments to determine a critical shift in applicator position. A 2 mm shift in the anterior and posterior directions was detrimental to the bladder and rectum, respectively and a 4 mm shift in all directions caused a critical reduction in HR-CTV cover-age. These findings indicate the importance of quality assurance practices that mitigate applicator displacement. Furthermore, the source localisation accuracy required for cervical brachytherapy was quantified. HDR gynaecological brachytherapy relies on 3D imaging, contouring, precise reconstruc-tion of applicator position and transfer of data to the afterloading device. To evaluate this process an end-to ....
