Abstract in Portuguese
Neste trabalho desenvolvemos um dispositivo que determina automaticamente a localização do centro do feixe de raios X e permite uma correta avaliação dos parâmetros dos sistemas radiológicos sem necessidade de alinhamento. O dispositivo desenvolvido-é baseado em sensores de silício; dispositivos mecânicos que executam uma varredura sobre o campo de raios X e computador portátil que analisa e apresenta os resultados no local da avaliação

Abstract in English
In this work we developed a device that determines the location of the center of the X ray beam automatically and allows a correct evaluation of the parameters of radiologic systems without the need for alignment. The developed device is based on silicon photodiodes; mechanical devices that execute a scanning on the field of X rays and portable computer that analyzes and presents the results for evaluation
