Abstract
A meat inspection device uses measurements at two x-ray energies to detect bone in meat samples by determining a mass ratio of bone to meat such as would provide a photoelectric absorption and Compton scattering consistent with the attenuation of the x-rays at the two energies. A relative proportion at different locations can be used to develop an image of the bone. The image can be used to determine whether a product has an unacceptable composition of bone.
