Abstract
This study presents preliminary results of dual energy imaging techniques in film digital radiography applicable for clinical use. The studies were carried out by single x-ray exposure as well as double exposure technique. The single exposure technique was accomplished by placing two sets of screen/film combinations in a single cassette with an energy separation filter between them. The two optimal energies defined as the largest energy separation between the high and the low energy image were selected by a computer simulation followed by an experimental verification. A humanoid and a wedge-shaped plastic phantom were used to test the image quality. The images on the films were digitized by a high resolution laser scanner. The quality of the separated images though slightly inferior to the double exposure technique, was acceptable for clinical application.
