DETERMINING CONDITION OF TISSUE USING SPECTRAL ANALYSIS. SpectraScience, September 12, 2013: US20130237842-A1

A system for determining a condition of a tissue of a patient body is described. The tissue is illuminated with an illumination wavelength by a light source. In response to the illumination, the tissue emits light. This emitted light is received at a detector that includes multiple diode sensors. Th ...
