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. 1, record 1, English, - dual%2Dphoton%20absorptiometry
