The Clarifi® Imaging System is the first non-contact, noninvasive microvascular assessment tool that uses a proprietary optical imaging technique — spatial frequency domain imaging (SFDI) — to measure tissue oxygenation and perfusion at the point-of-care in seconds. It quantifies and maps five hemoglobin biomarkers of oxygenation and perfusion, helping clinicians identify problems, manage patients, and personalize treatment to reduce ulcers and amputations.
