Advancing iris melanoma brachytherapy: Eye plaque models for Monte Carlo simulations and 3D dosimetric datasets

PURPOSE: seeds. ACQUISITION AND VALIDATION METHODS: voxels. Simulations under TG-43 conditions are also carried out. Doses are compared to previously published data for validation. DATA FORMAT AND USAGE NOTES: The eye plaque models will be distributed with egs_brachy on GitHub (https://github.com/clrp-code/egs_brachy), along with an input file to facilitate custom simulations. The dosimetric database (https://doi.org/10.5281/zenodo.14776641) is comprised of 3D dose distributions for each plaque type, simulation condition, and radionuclides. POTENTIAL APPLICATIONS: The iris plaque models enable custom simulations with the open-access egs_brachy code. The database of 3D dose distributions supports advanced dose evaluations, as recommended by AAPM Task Group 221 on Ocular Brachytherapy. Overall, this work supports adoption of model-based dose evaluations for brachytherapy as recommended by TG-186.
