ABSTRACT:
An x-ray beam is scanned through a sequence of subsections of a volume. At each position the x-ray transmission is measured at two energies. The resultant transmission signals are processed to produce a signal representing the projected amount of a specific material in the volume. The two energies are chosen so that the mass attenuation coefficients of bone and soft tissue are comparable to each other.
