Acceptance tests of diagnostic displays in a PACS system according to AAPM TG18.
In a filmless environment it is necessary to execute acceptance and constancy tests on monitors used for interpretation of medical images. Performances of Barco CRT MGD521 MKII, Barco LCD L685EX monitors have been evaluated. Acceptancepress were executed following AAPM Task Group 18 guidelines. Visual and instrumental evaluations of geometric distortions, reflections, luminances response, contrast, uniformity, resolution, angular response and veiling glare were made. Barco monitors showed optimal performances, while EIZO monitors were accepted with some reserve on their quality level. Finally a comparative evaluation between monitors and film (the actual gold standard) was performed by an interview of ten radiologists: the monitors showed a quality at least equal to film. These monitors are currently in use for routine medical interpretation.
