Concept for the implementation of Ru-106 eye plaque characteristics in treatment planning — •Michelle Stroth¹, Henning Manke¹, Dirk Flühs², and Johannes Albrecht¹ — ¹TU Dortmund University, Dortmund, Germany — ²Department of Radiotherapy, Essen University Hospital, Germany

Brachytherapy with Ruthenium-106 eye plaques is an effective method for successfully treating ocular tumours.
To minimize side effects due to irradiation of radiosensitive structures, such as the fovea and optic nerve head, a standardized treatment planning software is needed which considers every relevant therapy parameter. This includes the geometry of the treated eye, the plaque size and position, as well as the inhomogeneous surface dose rate distribution of an individual plaque.
Implementing a patient-specific eye model within Geant4-based Monte Carlo simulations allows for the generation of dose-volume histograms and, thus, for comparing different therapeutic approaches with various plaque types and positions. The general software concept for the investigation and implementation of the characteristics of Ru-106 eye plaques in treatment planning is presented.
