Google Research has developed PhotoScan, a deep learning framework that estimates body composition metrics like body fat percentage, Android-to-Gynoid fat ratio, and Visceral-to-Subcutaneous fat ratio using standard smartphone photos. This technology, trained on data from UK Biobank and a new cohort, shows accuracy comparable to DXA scans in predicting insulin resistance. PhotoScan aims to provide a scalable, non-invasive method for early metabolic risk detection, surpassing the accuracy of smartwatch-based bioelectrical impedance analysis sensors. AI
IMPACT Offers a scalable, non-invasive method for early metabolic risk detection using readily available smartphone technology.
