Abstract
The characteristic lines of molybdenum-anode x-ray tubes yield high contrast images on film of thin breasts. For thicker breasts, the higher spectral energies are transmitted and the lower energies are mostly absorbed, resulting in higher patient exposure and reduced contrast. However, filters from rhodium (Z=45) to tin (Z=50) can be used to shape the energy distribution of tungsten-anode tubes to improve contrast and reduce patient exposure. Measured spectra and phantom test data are described.
