The eye phantom that was projected represents one of an adolescent between 14 and 16 years. The phantom is constituted of equivalent tissues (TE) and can simulate the components of the human eye in the exposition to the radiation. Through the accomplishment of an radiodiagnostic image for computer tomography with axial section, in which the phantom of eye’s object was setting up in another phantom, an anthropomorphic and anthropometric head and neck phantom developed in the research group NRI, it was verified the equivalence of the tissues, comparative to an axial section of a computer tomography of a real eyes. The improvement resumes in the production of the equivalent tissue, due to dehydration factors in function of the time that committed the equivalence anthropometric and anthropomorphic of the same.
