Claim:
1. A method for generating a set of training data that is useful for determining tissue oxygenation in vivo, comprising: (a) providing a spectrometer comprising a probe having: (b) for a subject, placing the probe such that the light detector detects absorbance spectra of light reflected from or transmitted through a tissue of the subject, the detected absorbance spectra resulting from light emitted by the first and second light sources; (c) using the detected absorbance spectra to calculate a sum of a concentration of oxymyoglobin and a concentration of oxyhemoglobin in the tissue [oxyMbHb]; (d) using the detected absorbance spectrum to calculate a sum of a concentration of deoxymyoglobin and a concentration of deoxyhemoglobin in the tissue [deoxyMbHb]; (e) calculating tissue oxygenations from [oxyMbHb] and [deoxyMbHb]; (f) storing on a computer readable media: (g) repeating steps (b)-(f) for a plurality of subjects to generate a set of training data.
