Spectroscopic detection of brain damage

A method comprising:

• causing a directed light source comprising a plurality of wavelengths to produce multiple spectra, wherein the plurality of wavelengths comprises visible wavelengths through near-infrared wavelengths;
• determining, based on a relative intensity at each of the plurality of wavelengths for each spectrum, an intensity at each of the plurality of wavelengths and a spectroscopic lineshape for the multiple spectra;
• determining, based on a plot comprising the intensity at each of the plurality of wavelengths and the spectroscopic lineshape for the multiple spectra, a numerical value for a first intensity and a first slope selected from the plot, wherein the first intensity and the first slope are associated with one or more of the plurality of wavelengths;
• and
• determining, based on a control value for the first intensity and a control value for the first slope, that the numerical value for the first intensity and the numerical value for the first slope are indicative of brain damage in a patient.

An apparatus comprising:

• one or more processors;
• and
• a memory storing processor executable instructions that, when executed by the one or more processors, cause the apparatus to:
• cause a directed light source comprising a plurality of wavelengths to produce multiple spectra, wherein the plurality of wavelengths comprises visible wavelengths through near-infrared wavelengths;
• determine, based on a relative intensity at each of the plurality of wavelengths for each spectrum, an intensity at each of the plurality of wavelengths and a spectroscopic lineshape for the multiple spectra;
• determine, based on a plot comprising the intensity at each of the plurality of wavelengths and the spectroscopic lineshape for the multiple spectra, a numerical value for a first intensity and a first slope selected from the plot, wherein the first intensity and the first slope are associated with one or more of the plurality of wavelengths;
• and
• determine, based on a control value for the first intensity and a control value for the first slope, that the numerical value for the first intensity and the numerical value for the first slope are indicative of brain damage in a patient.
