The Discovery series bone densitometers are computer-assisted X-Ray scanners used to aid a physician in measuring bone mineral density (BMD) and determining fracture risk. All Discovery Series densitometers allow comparison of estimated BMD from a subject's proximal femur (hip), lumbar spine, and forearm to reference data for sex and ethnicity matched controls. Discovery Wi, W, and A models can also be used for estimating the lean body mass and fat mass of non-osseous tissues. Discovery C, W, SL, and A models can be used for performing a visual or quantitative assessment of vertebral bodies for diagnosis of vertebral deformity. Discovery SL and A models are capable of measuring the lateral vertebral BMD in the supine lateral position.
An assembly of devices designed for bone density measurements and other calculations based on data obtained using a two distinct photon energy peak. Also referred to as a bone densitometer. It utilizes an x-ray tube or tubes as the photon source which are mechanically aligned and moves along with a photon detector assembly typically in a rectilinear pattern. The collimated beam is directed through an anatomical region of interest and the differential absorption patterns are detected. This information is used in calculations to estimate bone mineral density (osteoporosis), subcutaneous fat, fracture risk.
