Abstract
THE fractional composition of a multi-component absorber can be determined from the attenuation of γ-radiation at several energies1–6. This technique has been used to measure the amount of bone in vivo7–11. We now show that absorption measurements at two energies accurately indicate the relative lean–fat composition of soft tissue, and we have developed a scanning method of determining fat, lean cellular and bone mineral mass in vivo.
