How BodyMetrix Works

The Platform
BodyMetrix is two parts that work together: the BX2K ultrasound wand and the BodyMetrix Software Subscription. They aren't sold or used separately, because the wand operates through the Software.

How the measurement works

1. The wand sends short sound pulses into the body at each measurement site.
2. The pulses reflect back from the boundaries between tissue layers: skin to fat, fat to fascia, and fascia to muscle.
3. BodyMetrix times how long each echo takes to return and converts that into a direct measurement of each layer's thickness.
4. The Software combines the site measurements using your selected formula to calculate body fat percentage.

This is A-mode (single beam) ultrasound.

Consistent results
BodyMetrix measures tissue directly. It doesn't estimate from fluid resistance, so results aren't affected by hydration, food intake, caffeine, exercise, or time of day. A 7 AM assessment before training and a 3 PM assessment after a session on the same client produce the same result.

Scans
Beyond the numbers, BodyMetrix creates a cross-sectional view of the tissue layers at each site, showing fat, fascia, and muscle in a single image. Scans can be compared visit after visit.

How long it takes

• 3-site protocol: about 90 seconds
• 7-site protocol: under 5 minutes

Intended use
BodyMetrix is intended for use on generally healthy adults and children 6 or older. It's not intended for diagnosis of any disease or condition.
