About Subtle Medical
Subtle Medical is the world leader in applying deep learning to medical image acquisition, enabling faster, safer, and smarter medical imaging across MRI, PET, and CT modalities. Founded at Stanford University by Dr. Greg Zaharchuk, a neuroradiologist and professor, and Dr. Enhao Gong, a deep learning scientist, the company was born from their shared passion for improving the quality and access of medical imaging through artificial intelligence. With over $85 million raised and more than 75 full-time employees, Subtle Medical has deployed its solutions on over 1,300 scanners across multiple countries globally. The company's flagship products include the Subtle-ELITE™ suite for MRI (featuring SubtleHD™, SubtleSYNTH™, and SubtleALIGN™), SubtleHD™ for PET and CT imaging, and AiMIFY™ in partnership with Bracco. These vendor-neutral solutions work on existing scanners, old and new, dramatically improving image quality while reducing scan times and enabling more efficient patient care. Subtle Medical serves radiology practices, imaging centers, health systems, and hospitals worldwide, with customers including RadNet, Precision Imaging Centers, Capital Health, and Middlesex Health. The company holds 11 FDA clearances, has 30+ issued or pending patents, and has published 25+ peer-reviewed papers demonstrating clinical evidence and outcomes. Their mission is to empower physicians and patients with safe and timely medical imaging that leads to improved outcomes and a higher quality of life for all.
