title: Seed localization in eye plaque brachytherapy.
abstract: We describe a simple method for localizing seeds in eye plaques used for brachytherapy treatment of intraocular tumors and age-related macular degeneration. The method is based on obtaining magnified photocopy images of plaques with seeds in place and then using simple geometrical considerations to reconstruct seed coordinates with about 2% accuracy. A spreadsheet program is used for reconstruction and dosimetric calculations.
