Definition
A scanning technique which directs alternating X-ray energy from two separate sources (high energy and low energy) towards bone at a set frequency. The amount of these x-rays that pass through the bone is measured for each beam and bone mineral density is determined based on the difference of the two transmitted X-ray beams.
