To see beyond


Modulim’s groundbreaking technology noninvasively measures key biomarkers — tissue oxygen saturation and the concentration and distribution of hemoglobin in the papillary (superficial) and reticular (sub-surface) dermis. This provides clinicians greater insight into oxygen availability and extraction to localized tissue — vital information when caring for patients with compromised circulation.


Every wavelength of light has a signature color. The color of objects in the everyday world are a direct result of how they interact with light. Objects appear to be different colors because they absorb some wavelengths of light and reflect others. We all see color differently and often misinterpret the differences between pigments (absorption) and opacity/translucency (scattering). In a clinical or diagnostic setting, that variation and subjectivity in color interpretation can be risky.

Our patented technology—spatial frequency domain imaging (SFDI)—takes the guesswork out of characterizing biological tissue by allowing clinicians to quantify key tissue health biomarkers, objectively and precisely.

Modulim’s technology:


  • Quantifies local hemoglobin distribution and oxygenation in tissue layers over a wide area.
  • Differentiates between layers of tissue and components due to absorption and scattering.
  • Is noninvasive, non-contact, and non-ionizing—which means it does not expose patient to harmful radiation.
  • Works significantly faster than traditional imaging—and generates images in seconds.
  • Is easily repeatable to monitor progression of disease or results of treatment.
