CHEST RADIOGRAPHS WITH THE AMBER SYSTEM

Since April 1990, chest radiographs in the Mannheim clinic have been p erformed with a slit technique (Kodak AMBER System). In this study, im age quality from conventional film/screen combination and from storage phosphor radiography was compared with that from the AMBER system. Ph antoms were used to measure spatial resolution and to determine the de tectability of nodules. Image quality affecting various structures wit hin the thorax was evaluated on 200 p.a. and 48 lateral radiographs by three radiologists from Mannheim and four from Berlin. In the retroca rdiac, retrodiaphragmatic, mediastinal and peripheral portions the bes t image quality was obtained by film/screen with the AMBER system. Com pared with conventional film/screen images, there was no improvement f rom the AMBER system within the lung parenchyma. The use of storage ph osphor plates with the AMBER system did not lead to any further improv ement in image quality.
