Key Points

  • The research aims to evaluate the effectiveness of a new dosimetry system for accurate dose measurement in Ru-106 plaque brachytherapy.
  • Developed a flexible film dosimetry system (PFD) for dose measurement
  • Conducted planar and central axis (CAX) measurements
  • Compared results with manufacturer-certified reference data for validation
  • Showed strong agreement between PFD measurements and reference data
  • Demonstrated high-resolution dose measurements on curved plaque surfaces
  • Provided a reproducible solution for commissioning and quality assurance in clinical settings

Abstract

The PFD enabled accurate and high-resolution dose measurements on the curved surfaces of Ru-106 plaques. Both planar and CAX measurements demonstrated strong agreement with manufacturer-certified reference data across all plaque types. This system offers a practical and reproducible solution for commissioning and QA in Ru-106 plaque brachytherapy, supporting its clinical integration for choroidal melanoma treatment.
