Importance of computed radiography image display parameters in orthopedic imaging

摘要

Abstract: study, we used a DuPont Linx CR system to generate film images of the AP & lateral views of a foot phantom. Images were printed using a 2 on 1 CR image output format. Image display parameters for one of these two images was varied in a systematic fashion while the second image remained at the constant default settings recommended by the manufacturer. Twelve radiologists evaluated the relative image quality of each pair of images for four anatomic areas: osseous detail in the fore foot, mid foot and hind foot, and soft tissue detail. The resultant data were analyzed to investigate the influence of the display parameters on radiologist preference. The results of this study demonstrate that significant improvements are achievable for the CR display parameters when compared to the default values. This improvement in radiologist preference depends on the anatomical regions under consideration.!6
