Abstract

The use of narrow x-ray spectra to produce the radiographic image allows a reduction in patient exposure without any appreciable degradation in image quality. When this method is combined with the use of rare-earth intensifying screens, the performance of the screens is improved primarily in terms of patient exposure. A number of screens have been tested in a case of bone imaging with aluminum filtered beams and with ytterbium filtered beams. A summary of the results in terms of radiation doses and image quality is presented.
