Ultrasound and Tissue Thickness Measurement
Ultrasound as a tool for measuring tissue structure and in particular fat and muscle thickness has been studied and validated extensively since the 50's.
The BodyMetrix™ uses the same underlying science to produce accurate tissue thickness measurements.
Ultrasound and Body Composition
Ultrasound was first used to measure body composition in the 80's.
Measuring fat thickness at multiple sites has proven to be an accurate technique to measure body compositon (%BF). The benefit of ultrasound is that you can also measure muscle thickness directly. Ultimately BodyMetrix™ body composition measurements will use both fat and muscle thickness to increase accuracy.
Below are summaries of several studies which have compared the BodyMetrix™ to DEXA, BodPod, Hydrostatic, and Bio-impedance. The studies show good agreement with these more expensive and non-portable systems.
