Bone density scan. Physiologist using a dual-emission X-ray absorptiometry (DXA) scanner to measure the bone density of a research volunteer's spine. DXA scans are used to measure a patient's bone mineral density (BMD) by comparing the results from two X-ray beams of differing energy. They are typically used to diagnose and assess the effects of osteoporosis in women.
