Densitometers, Bone, Isotope, Dual-Photon Absorptiometry
Definition : Isotope bone densitometers that use two sources to yield a dual-energy (two discrete line spectra) beam of gamma rays (x-ray photons). In addition to the dual photon sources, these densitometers typically include a scanner, a dual-channel analyzer, and a computer with appropriate software. Dual-photon densitometers are used to assess bone mineral content in the axial skeleton, usually by measuring the lumbar spine and the hip region, including the proximal femur.
