Paper Abstract

A Du Pont Linx computed radiography (CR) system and associated radiology image viewing station (RIVS) were evaluated with respect to CR image data transfer and image quality performance. Image transfers were compared with conventional film digitizers and CR film processing. Image quality was determined using limiting spatial resolution and low contrast detectability. Processing times differed for CR film output and softcopy display on the RIVS station, ranging between 2 and 10 minutes depending on whether single or batch processing was being used. In general, images from the CR were available on the RIVS display within 100 to 160 seconds compared with a minimum of 270 seconds for producing CR film images. Low contrast detectability performance for CR films was strongly influenced by choice of CR image processing algorithm. In general, there was very little difference between CR film and the corresponding images displayed on a RIVS. Digitization of film and subsequent review on a RIVS, however, generally showed a marked deterioration in low contrast detectability performance.
