DIGITAL RADIOGRAPHY - COMPARISON OF DIFFERENT METHODS FOR IMAGING OF THE THORAX AND THE GASTROINTESTINAL TRACTS

In evaluating the image quality of the chest, four different analog an d digital methods were compared. For peripheral lung field, the advanc ed multiple beam equalization radiography (AMBER) system was given the best score, followed in order by the storage phosphor, conventional, and asymmetric film/screen systems. For the mediastinal field, the hig hest image quality was given to the AMBER system, followed by storage phosphor and asymmetric film/screen system. The best overall image qua lity, especially with regard to demonstration of pathologic alteration , was given to the AMBER system, followed by the storage-phosphor, con ventional, and asymmetric film/screen radiography systems. In conclusi on, AMBER demonstrated the highest image quality. The storage-phosphor system provided better results in the peripheral and mediastinal fiel ds in comparison with conventional film/screen systems. Other digital systems in eluding selenium chest radiography system and image intensi fier digital radiography were also discussed. Copyright (C) 1995 by W. B. Saunders Company
