Densitometers are the devices that are used to measure the optical density of quite a lot of opaque objects. A bone densitometer measures the bone mass that helps to measure the risk elements associated to fracture and other bone problems. Bones are composed of calcium and other minerals. reduction in amounts of any of these minerals could result in extreme orthopedic stipulations. Bone densitometers quantify the presence of these minerals within the bones. Bone densitometers are much like X-ray scanners however are facilitated with two X-ray beams. These beams are of different wavelengths, a excessive energy beam and a low energy beam. the quantity of energy that’s not able to pass in the course of the bone leads to the formation of spots in the photographic plate. These spots information the physicians concerning the orthopedic density and different stipulations. Bone densitometers are used majorly to discover osteoporosis. Bone densitometers will also be segmented as peripheral and axial bone densitometers. Peripheral bone densitometer helps to quantify the density of peripheral skeleton whereas; the axial skeletal density is quantified the use of an axial bone densitometer.
