Utilization of a homogeneous phantom of extremities for radiographic images standardization

This work aims at the utilization of a homogeneous phantom, allowing to simulate absorption and scattering of the radiation next to a patient's extremity. Homogeneous phantom will be used in the time-scale sensitometric method to evaluate the sensitivity of screen-film systems. These radiographic techniques will be applied, in the future, to anthropomorphic phantom for extremities, leading to the achievement of a better radiographic technique, with a lesser dose for the patient and the reduction of cost of a radiodiagnostic job. By standardizing the radiographic techniques, it is possible to decrease the number of rejected films and reduce the charge of the equipment tube. (author)
