- Abstract
Eye plaque brachytherapy is a radiation therapy technique designed for treating ocular cancers. Current clinical radiation dose evaluations for eye plaque brachytherapy involve considerable assumptions, resulting in inaccurate doses. This thesis aims to advance dose evaluations for eye plaque brachytherapy by implementation of detailed models for various photon and beta plaques in the egs_brachy Monte Carlo code. Calculated dose distributions are verified against published results. These plaque models and dose distributions will be distributed to the medical physics community. Dose distributions are calculated for different scenarios (clinical assumptions; plaque in water; plaque in realistic eye model). These results confirm the importance of model-based calculations for photon plaques and show that modelling tissues should be considered for beta plaques. Finally, dose distributions for photon and beta plaques are compared, demonstrating the potential of model-based dose evaluations in future studies.
