Body Fat Measurement

BodyMetrix Ultrasound Body Fat Measurement

Body fat measurement using the BodyMetrix Ultrasound System

The BodyMetrix body fat measurement system combines a clinical hand-held ultrasound wand with innovative software to accurately and consistently assess and monitor your body composition. The BodyMetrix Ultrasound System is fast, non-invasive (no painful or embarrassing pinching) and highly accurate. It is also not sensitive to hydration, exercise level or caffeine intake, allowing consistent results. In addition to precise body fat percentage, this technology can scan, see and track fat loss and muscle gain.

Before the BodyMetrix System, the only way to accurately track fat loss and muscle gain was with large and expensive x-ray CT and MRI machines.

The BodyMetrix System provides instant comprehensive reports:

  •  Body Fat%
  •  Body Scans (To track fat loss and muscle gain)
  •  Point-Specific Measurement Thickness
  •  Circumference Measurement Record
  •  Waist-to-Hip Ratio
  • BMR (basal metabolic rate)
  • BMI (Body Mass Index)
  • Relative Risk of Disease
  • Lean body mass
  • Brief Health Assessment Reporting

How does it work?

The BodyMetrix works by using ultrasound. When ultrasound waves penetrate tissue, reflections occur at different tissue boundaries. For example, strong ultrasound reflections exist at the fat-to-muscle and the muscle-to-bone interfaces.

Ultrasound allows the BodyMetrix to detect the fat thickness at each measurement point. An accurate body fat percentage can be determined by making measurements at multiple points on the body.

The graph above shows a typical measurement. The horizontal axis corresponds to the thickness or depth of tissue, and the vertical axis is the reflected signal. The first peak (1) is the fat-muscle boundary. The smaller peaks (2) are different structures, which can include connective tissues in the muscle layer. The third peak (3) is the muscle-bone border.

It’s important to note that the BodyMetrix measures the actual tissue thickness, unlike callipers, which measure a skin fold thickness, which can be anywhere from 1 to 3 times the actual fat thickness.
