Dual-photon absorptiometry for determination of bone mineral content in the calcaneus with correction for fat.
A portable dual-photon absorptiometry system for the determination of the bone mineral content BMC in vivo in the calcaneal bone is described. With knowledge of the total thickness of the heel at the measuring point the BMC can be corrected for fat and lean soft tissue. The system is capable of measuring the BMC in the heel bone with a precision of 1.2% in vitro and 1.8% in vivo at an absorbed dose to the skin of 0.2 mSv.
