Dual-energy X-ray absorptiometry: Measurement, Bone density measurement & Physics

Dual-energy X-ray absorptiometry (DXA or DEXA; also BMD test, bone density test, bone densitometry, p-DEXA) is a means of measuring bone mineral density (BMD) with spectral imaging. Two X-ray beams, with different energy levels, are aimed at the patient's bones. When soft tissue absorption is subtracted, the bone mineral density (BMD) can be determined…
