  This study aimed to develop and characterize a low-cost anthropomorphic orbital phantom based on epoxy resin tissue-equivalent materials for computed tomography (CT) and radiation therapy applications. The phantom incorporated four main orbital structures, including orbital bone, extraocular muscles, optic nerve, and crystalline lens, using optimized epoxy-based composite formulations. Radiological characterization was performed through effective atomic number, electron density, mass attenuation coefficient, and CT number analyses over energy ranges extending from 10KeV to 25 MeV. In the diagnostic energy range (60–200 keV), the average deviations in mass attenuation coefficients were approximately −1.2% for orbital bone, +1.6% for the crystalline lens, −0.2% for extraocular muscle, and −0.3% for the optic nerve. At high energies (200 keV–25 MeV), the ave.. Read More»
