US Patent Issued on Nov. 3 for "Tissue oximeter with stored simulated reflectance curves" (California Inventors)

ALEXANDRIA, Va., Nov. 3 -- United States Patent no. 12,778,464, issued on Nov. 3.

"Tissue oximeter with stored simulated reflectance curves" was invented by Kate LeeAnn Bechtel (Pleasant Hill, Calif.) and H. Keith Nishihara (Los Altos, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method for determining oxygen saturation includes emitting light from sources into tissue; detecting the light by detectors subsequent to reflection; and generating reflectance data based on detecting the light. The method includes determining a first subset of simulated reflectance curves from a set of simulated reflectance curves stored in a tissue oximetry device for a coarse grid; and fitting the reflectance data poin...
