Three-dimensional optical (3DO) imaging using the Fit3D ProScanner is a sensitive and accurate tool for monitoring longitudinal changes in body composition (total fat mass, fat-free mass, and appendicular lean mass) compared to dual-energy X-ray absorptiometry (DXA).

Use 3DO imaging (like Fit3D) to track your body composition changes over time rather than relying solely on scale weight. The technology is validated to detect small changes in fat and lean mass comparable to clinical DXA scans. For best results, take multiple scans and average them to minimize error, and focus on trends over weeks rather than day-to-day fluctuations.

GoodSupportsHIGH confidence
As compared to DXA, 3DO was highly sensitive in detecting body shape changes over time. The 3DO method was sensitive enough to detect even small changes in body composition during intervention studies.
