Mammography instruments

Mammography dose meters

Mammography dose meters/chambers are calibrated at diagnostic mammography kV settings using a diagnostic mammography X-ray set with Molybdenum anode, and 0.03 mm Molybdenum filtration. The air kerma rates used are directly traceable to the UK primary standards facility at the National Physical Laboratory (NPL).

Mammography kVp meters

Mammography kVp Meters are calibrated against diagnostic mammography energies. The traceable peak accelerating voltage is obtained from an invasive kV divider which is, in turn, cross referenced against the measured X-ray spectrum end point (peak photon energy). This is obtained using a hyper pure germanium detector.
