Abstract
Single and dual-energy x-ray images are obtained in a single scanning procedure, which allows measurement of bone density from the scan information acquired at both energy levels and high resolution digital geometric images from one of the two energy level scan sets. Densitometric and geometric measurements taken from multiple projections may be combined to create three-dimensional densitometric and tomographic images. An interface device allow an operator to select one of a plurality of scanning sequences which correspond to scanning a set of regions of interest in the patient.
