This excerpt was created in the absence of an abstract.

The introduction of a dual-track anode X-ray unit for mammography (IGE Senographe DMR) prompts some consideration of the optimization of X-ray spectra used for this examination on existing units. A considerable number of the X-ray units used for screening and symptomatic mammography in the UK and elsewhere employ a molybdenum anode tube with molybdenum filtration, usually 0.03 mm thick, using a tube potential of around 30 kVp.
