Abstract
A technique enabling in situ measurements of the spectrum of X-ray tubes employed in mammographic screenings is described. The technique involves the use of a commercially available CCD camera and a set of metal foils and is particularly useful to perform a fast evaluation of the spectral properties of a Mo anode mammographic system operating at standard flux levels. A description of the detector calibration procedure is first given, followed by a discussion of the study and choice of an appropriate set of X-ray attenuation foils. Finally, the use of the system for a spectroscopic characterization of a mammographic system is reported.
