Abstract

The use of a diffraction spectrometer developed by Deslattes for determination of mammographic kV is extended to the measurement of accurate, relative x-ray spectra. A series of x-ray spectra were acquired by passing an x-ray beam through a bent-silicon diffraction crystal, and the diffracted x-rays were detected by a charge coupled device (CCD) coupled to an x-ray scintillating screen. The raw spectra were corrected both on the energy axis and on the x-ray photon fluence axis. The measured, corrected x-ray spectra were compared against tabulated x-ray spectra measured under similar conditions. Results indicate that the current device is capable of producing accurate relative x-ray spectra in the mammography energy range.
