The basic principle involved in dual-photon absorptiometry (DPA) for the measurement of bone density was the same as for single-photon absorptiometry: quantifying the degree of attenuation of a photon energy beam after passage through bone and soft tissue. In dual-photon systems, however, an isotope, which emitted photon energy at two distinct photoelectric peaks, or two isotopes, each emitting photon energy at separate and distinct photoelectric peaks, were used.
