Portable Ultrasonic Bone Densitometer
Bone densitometry is an increasingly important diagnostic tool as baby boomers come of retirement age. This technology has proven to be comparable in accuracy to X-Ray densitometry without the negative effects of radiation. Furthermore, ultrasonic instrument costs are low enough for use in physician offices, enabling a large segment of the population to be assessed and monitored before bone loss reaches critical levels.
