Abstract
This paper describes a system which approaches the state-of-the-art in energy dispersive x-ray spectrometry. Special methods for obtaining x-ray spectra from machines operating at high current levels and other phenomena which could cause spectral distortion are discussed. Entrance and exit spectra from some typical diagnostic procedures are shown. It is demonstrated that the exit spectra can be closely approximated by replacing the phantom with aluminum filtration. Since the sensitometric performance of imaging systems is influenced by beam quality, this technique can provide x-ray beams similar to those used in diagnostic radiology. The usefulness of the spectrometer for accurately measuring kVp and determining unknown elements of an intensifying screen is also illustrated.
