1. A method for calibrating detectors of a tissue oximetry device comprising: emitting light from a light source into a tissue phantom; detecting in a plurality of detectors the light emitted from the light source, subsequent to reflection from the tissue phantom; generating a set of detector responses by the plurality of detectors based on detecting the light emitted from the light source; comparing the set of detector responses and a reflectance curve for the tissue phantom; generating a set of calibration functions based on comparing the set of detector responses and the reflectance curve, wherein each calibration function in the set of calibration functions is associated with a unique, light source-detector pair; and storing the set of calibration functions in a memory of the tissue oximetry device.
