Dual-energy CT imaging of orbits during episcleral brachytherapy with Ru-106 plaques: A phantom study on its potential for plaque position verification

Despite the increasing popularity of advanced external beam radiotherapy techniques such as proton therapy and radiosurgery, radioactive plaque brachytherapy remains the dominant vision-preserving treatment for intraocular tumors [1,2]. Nowadays, the most widely used eye brachytherapy plaques are gold shells with embedded seeds of a low-energy γ emitting radionuclide such as I-125, Pd-103, and Cs-131 [1–3]. Prefabricated solid silver or platinum shells encapsulating a pure b-emitter such as Ru-106/Rh-106 and Sr-90/Y-90 are also widely used for ocular tumors
