Abstract
The diagnostic image quality of a Philips' Picture Archiving and Communications Subsystem (PACS) was investigated by means of a Receiver Operating Characteristic study as a contribution to the current Dutch PACS research project. Conventional films and laser- and videodigitized images were compared for diagnostic image quality. A test series of 68 posterior-anterior (PA) screen film roentgenograms of a 3M chest phantom with superimposed simulated interstitial pattern disease were produced. The conventional test films were dig;tized using a video- and laser digitizer. The series of conventional and laser- and videodigitized images were viewed by four experienced radiologists. The digitized images were displayed on a 60 Hz interlaced monitor with 1024 lines. The relative ranking in terms of decreasing ROC areas was respectively conventional, laser- and videodigitized images.
