Comparação das curvas sensitométricas dos anos: 2000, 2002 e 2004 de instituições de saúde do Estado de São Paulo

Abstract

Quality assurance of the radiographic images concerning to film processing and dark room installation conditions is essential for the health professionals in order to get a good image and consequently give a good diagnostic. The “Portaria 453” from June/1998 from the act of Brazilian Sanitary - Inspection Secretary of the Health Department [1] determines that every radiology institution must have a Quality Assurance Program, which includes the quality assurance of the film processing and dark room installation conditions. In these work 507 technical reports of health institutions of the São Paulo State in Brazil, complying the total of 600 sensitometry curves from radiographic films, obtained from the SAPRA Assessoria data, were analyzed with the purpose of showing a comparative study between the real conditions of the health institutions and conditions required by the Sanitary - Inspection Secretary of the Health Department through, first of all, the Resolution SS.625 from 1994 of the Sanitary Inspection Center of the São Paulo State, and nowadays the “Portaria 453” from June/1998 of Brazil. In this study was found a sensitive improvement in the last few years, particularly 2000, 2002 e 2004, in most of the analyzed institutions concerning to film processing conditions, implantation of automatic processing and the processing parameters as H&D curves due to implantation of the Resolution SS.625 — São Paulo State and the “Portaria 453” - Brazil.Keywordsquality controlradiographic filmfilm processorsensitometric method
