Body Fat Measurement

BodyMetrix Ultrasound Body Fat Measurement

The BodyMetrix System combines a clinical hand-held ultrasound wand with innovative software to accurately and consistently assess and monitor your body composition. The testing is fast, non-invasive (no painful or embarassing pinching) and is highly accurate. It is also not sensitive to hydration, exercise level or caffeine intake allowing consistent results. In addition to accurate body fat%, with this technology we 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, there are strong ultrasound reflections at fat-muscle and muscle-bone.

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

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 structure 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 true tissue thickness unlike calipers which measure a skin fold thickness which can be anywhere from 1 to 3 times the true fat thickness.

Body scans to track fat loss and muscle gain:










These  images are body scans generated using the BodyMetrix. Both scans are of the front right side of a client’s thigh, scanning from the midpoint of the thigh down towards the top of the knee, approximately 6-7 inches.  In the before scan, the average fat thickness in that area was 11.5mm and the average muscle thickness in that area was 30.0mm.  In the after scan, the average fat thickness in that area was 7.4mm and the average muscle thickness in that area was 35.4mm.  Overall, this client’s total fat loss averaged 4.1mm and the average muscle gain was 5.4mm. These scans can be saved for future comparison to accurately track changes in fat and muscle thickness.
