  • Organ or tissue hemodynamic and metabolic function measured using super-continuum light sources
    Patent number: 12089945
    Abstract: An apparatus is described for measuring hemodynamic or metabolic function of an organ or tissue region of a subject comprising a super-continuum laser operating in the near or short-wave infrared wavelength range and comprising a multi-stage amplifier. A source fiber delivers the super-continuum emission to the organ or tissue region, and a collection fiber receives reflected emission from the region. A detector followed by a processor is used to determine a metabolic state and an oxygenation state of the organ or tissue region. A signal-to-noise ratio of the signal is improved using a dual-arm differential measurement technique.

  • Brain metabolism monitoring through CCO measurements using all-fiber-integrated super-continuum source
    Patent number: 11529091
    Abstract: Techniques for measuring metabolic tissue state and oxygenation in human or animal models, through optical techniques capable of simultaneous measurement at single region of interest. Simultaneously measuring CCO, oxygenated hemoglobin (HbO), and deoxygenated (HbR) hemoglobin is performed and metabolic activity of the tissue is determined. The methods employ a super-continuum light source and a probe to deliver light to the individual, and reflected light from the individual is analyzed to determine the metabolic function of the individual.
