Dosimetric verification of HDR vaginal cylinder applications using Gafchromic film and Monte Carlo simulation with a custom phantom
This study demonstrates that EBT3 film dosimetry using an in-house phantom offers a practical and reliable method for verifying prescription doses in HDR vaginal cylinder treatments. MC simulations provide a strong theoretical complement and together, this approach strengthens confidence in dose accuracy and support robust QA in HDR-BT for gynecological cancers.
