Characterization and analysis of the physical parameters in dental X-rays phantom

Abstract

All care related to ionizing radiation exposure to patients, the radiographic image quality and gain time is related to quality control equipment and image. Therefore, it is necessary to be realized by using quality control and intercomparison phantom images with the results of previous tests as well as other types of X-ray equipment, or performing the intercomparison of results of quality control testing. The objective of this study was to characterization, and analysis (intercomparison) results periapical radiographs obtained with phantom and evaluate the high and low contrast in dental radiographs service of Maraba, northern Brazil. For the intercomparison of physical parameter of high and low contrast in the periapical radiographic equipment of the Maraba, a phantom developed in Brazil was used precisely in Aracaju, northeastern. It is worth noting that, the phantom used in this work and the interparameter of the equipment of the images showed satisfactory results bringing out the difference from the standard image. However, tests can be used to switch to other equipment in the surrounding towns of the city of Maraba. Thus allowing the cornerstone for the creation of a database with images obtained with the phantom and can be used in training of students and dental professionals.
