[A protocol for evaluating screen-film systems].
When a competition is made for the supply of sensitive photographic material, each USL is asked, in a time scan of one or more years, to evaluate the characteristics of the screen-film systems proposed by the various companies. In the last years the authors had several opportunities to check different screen-film systems for many Friuli-Venezia Giulia hospitals. For this reason they have set an evaluation form tested after following changes and recently employed in its final version. The check form is reported on in this paper with some personal considerations originated by the authors' experience. The technical parameters which must be evaluated are reported, together with the instrumentation needed to perform the technical examination, the examination modality, and the score-attributing criteria. The evaluation form is very flexible for it allows each Radiology Department to evaluate each parameter in a personal way and to fit it to its own needs.
