What is 3D optical imaging (3D body scanning) and how does it work?

Overview

3D optical imaging — also called 3D body scanning — is a non-invasive technology that produces a three-dimensional image of the body. The client or patient simply steps onto a turntable and rotates while a camera captures images from all angles. Using AI-driven algorithms, the system automatically calculates both anthropometric measurements (circumferences, lengths) and body composition metrics in under one minute.

How a Scan Works

1. The client steps onto the rotating turntable.
2. The turntable rotates while the camera captures images of the body from multiple angles.
3. AI-driven algorithms process the images and calculate measurements automatically.
4. Results — including circumferences, lengths, and body composition data — are available in under one minute.

What the Technology Measures

• Anthropometrics — body circumferences and lengths, accurate to within ⅛ inch (less than 0.5 cm)
• Body composition — fat mass, lean mass, and related metrics
• Bone mineral content — estimated from the 3D scan

Notes

• Traditional tape measure variability for the same measurer on the same person can range from 0.5–9 cm. 3D optical imaging reduces this variability significantly, making results more consistent and reliable.
• Styku's body composition results have been published in peer-reviewed research demonstrating a correlation of 0.95+ with DEXA for fat mass, with DEXA considered a gold-standard measurement method.
• 3D optical imaging is the only single technology that captures both anthropometric and body composition data simultaneously.

If this resolves your issue, no further action is needed.
