Comparative Evaluation of Four Stereotactic Radiosurgery Planning Approaches for Treatment of Posterior Choroidal Melanoma

Journal of Medical Radiation Sciences, EarlyView.
This study evaluated four stereotactic radiosurgery planning approaches for posterior choroidal melanoma (CM). Analysis of thirteen CM cases resulted in a clinically meaningful reduction in dose to the brain for Brainlab Elements modulated arcs (BE) and Varian Eclipse HyperArc modulated arcs (HA) compared to Brainlab iPlan dynamic conformal arc therapy
