Previously dba as Modulated Imaging Inc., in the Spring 2019, management changed the firm's name to Modulim and moved to larger facilities. A pioneer in subsurface optical imaging powered by spatial frequency domain imaging (SFDI), the firm is defined by an advanced imaging technique co-invented by the firm senior management, SFDI deciphers the reflection, absorbance, and scattering of light in tissue to more accurately measure key biomarkers for assessing tissue health. The proprietary technology helps clinicians identify compromised circulation and perfusion by measuring microvascular tissue oxygenation and hemoglobin concentration and distribution. This approach is designed to help clinicians identify patients with compromised circulation for earlier intervention having the potential to save thousands of limbs and lives with a major reduction in treatment costs.
