title: Verification of source position in interstitial and intralumenal brachytherapy.
abstract: In brachytherapy afterloading, the treatment is simulated using dummy sources. In this study, imaging during treatment was performed to see whether the radioactive sources accurately replaced the dummy sources. In low-dose rate afterloading (manually or remote controlled) X-ray radiography was applied for verification. In high dose rate afterloading, the radioactive source was visualised under remote controlled X-ray fluoroscopy. Differences between dummy and treatment source position were observed, justifying verification imaging in brachytherapy.
