A body composition measurement device and method, particularly for soft tissue, are useful to determine levels of hydration or percent body fat, for example. It relies on the X-ray absorption analysis for a single energy or two or more energies. If only a single energy is used, then the length of the x-ray path through the soft tissue of the patient is measured. In one embodiment, body composition measurement device comprises measurement calipers, with the x-ray source and detector located on each caliper arm. The calipers determine the path length. As such, a controller either in the calipers or external to it can combine the information from the calipers and the detector to provide an indication of the body's soft tissue composition along the path.
