title: Compatibility characteristics of five radiographic films utilised in Brazilian diagnostic radiology.
abstract: To evaluate the quality of the radiographic films in Brazil, according to the recommendations of ISO 9236-1, a radiographic images simulator was used. A study of the control of the quality in radiographic films was implemented. With regard to this study, the results of five films of different manufacturers are presented. The characteristic curves for the ISO qualities of 55, 70, 90 and 120 kV are presented. The PTW REX simulator was used to determine the image quality parameters. Film 2 presents problems due to high sensitivity. Film 1 has a higher energy dependence than the other films. Film 5 yields the best results for almost all the sensitometric parameters. In conclusion, existing films in the Brazilian market vary considerably with relation to image quality.
