Abstract

Use of ultrasound (US) and fundus photography is the current imaging standard for determining tumor involvement, location, and dimensions for uveal melanomas. From this information, episcleral brachytherapy isodose plans, based on the Collaborative Ocular Melanoma Study (COMS), are generated on two-dimensional (2D) models of a standard eye with anatomic structures, e.g., macula and optic disk, identified as points of interest in a single plane. We have developed a magnetic resonance (MR) imaging technique for patient-specific tumor and anatomic definition of the eye, and for three-dimensional (3D) COMS-based isodose planning.
