Abstract
A method and apparatus for measuring bone density is disclosed. The method and apparatus use high-energy and low-energy images of hard-tissue and soft-tissue references to determine characteristics of hard and soft tissue under high-energy and low-energy radiation. Then, high-energy and low-energy x-ray images of the subject are processed to compute the density of the bone inside the subject.
