Standards in clinical dual energy x-ray absorptiometry
Dual Energy X-ray Absorptiometry (DXA) is a digital x-ray technique designed to quantify bone mineral density (BMD), primarily of the lumbar spine and hip, and hence to provide a measure of bone strength and propensity to fracture. The original technology was based on a pencil beam x-ray source but …
