Abstract
An evaluation of the image quality of scanning equalization radiography (SER) of the chest was conducted with 60 volunteer patients. Posteroanterior chest radiographs by SER and conventional methods were compared by six radiologists to determine the adequacy and uniformity of the film exposure and the visualization of normal anatomic structures. The radiographs by the SER technique were deemed to be superior for visualization of most anatomic features. With SER there were no film artifacts from the scanning technique and there was only occasional blurring of some structures with a 4.7-sec scan time.
