the clinical gold standard.
QuadraScan turns four smartphone photos into a detailed body profile in about 10 seconds, with no lab, no appointment and no special equipment.
Body dimensions, including lengths, widths and circumferences, plus key health proportions like waist-to-height ratio.
Body composition: lean mass, fat mass and bone mineral content. These come from proprietary AI models trained on clinical DXA scans.
In testing against a few thousand DXA scans, QuadraScan showed strong agreement for lean mass and fat mass. In head-to-head testing, its estimates landed within about 2 kg of DXA on average.
VIO Med Spa uses QuadraScan to track body composition changes in patients on GLP-1 programs, providing objective, visual data to support better care and stronger patient engagement.
Example patient report
Since her baseline scan, Taylor M. (27, GLP-1 program) is down 10 lbs, and her waist, chest, and BMI are all trending in the favorable direction.

They are not FDA-cleared or FDA-approved medical devices and are not intended to diagnose, cure, treat, prevent, or screen for any disease or medical condition, including but not limited to sarcopenia, osteoporosis, or obesity.
Body composition outputs, including lean mass and bone mineral content estimates, are derived from AI-based image analysis and are not equivalent to measurements obtained by DEXA scanning, MRI, or other clinically validated diagnostic modalities. All data generated by QuadraScan is intended to provide informational body composition and anthropometric measurements to support, but not replace, the professional judgment of a qualified healthcare provider.
No physician-patient relationship is established by use of the Fit:match platform. Clinical decisions regarding diagnosis, treatment, surgical planning, or disease management should always be made by a qualified healthcare professional using appropriate clinical tools and methodologies.
