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.
