MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202617075281 A) filed by Cmr Surgical Limited on June 18, 2026, for Determining Oxygenation Of Imaged Tissue.
Inventor includes Springett, Roger James.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: A method of determining the concentration of oxyhaemoglobin HbO2 and deoxyhaemoglobin Hb in an imaged tissue. The method comprises receiving a measured attenuation spectrum comprising n light attenuation measurement sets of the imaged tissue. Each light attenuation measurement set is at a different one of n wavelength bands. Each light attenuation measurement set comprises a plurality of light attenuation measurements, one for each pixel or group of pixels in the image of the tissue. The received measured attenuation spectrum is fit to a model attenuation spectrum which comprises a linear combination of a haemoglobin spectrum and a linear background spectrum. A set of n simultaneous equations are solved, each equating a light attenuation measurement set to the model attenuation spectrum for the wavelength band of the light attenuation measurement set. Solving comprises determining values of the concentration of oxyhaemoglobin HbO2 and deoxyhaemoglobin Hb and background coefficients which causes the measured attenuation spectrum to best fit the model attenuation spectrum.
