Claim Text:
1. A method of imaging, comprising: generating incident light including excitation light with an excitation light source, wherein the excitation light source comprises an epi-illumination light source; directing the incident light toward a tissue; receiving the incident light with a light detector after the incident light has interacted with a tissue; receiving emitted light with the light detector, wherein the emitted light is emitted from the tissue; generating an excitation image of the tissue in response to received incident light, wherein the excitation image is obtained at a wavelength of the excitation light, wherein the excitation light is near-infrared light; generating an un-normalized emitted light image of the tissue in response to the received emitted light, wherein the un-normalized emitted light image comprises an un-normalized fluorescence epi-illumination image generated at a selected wavelength different than the wavelength of the excitation light; and dividing the un-normalized emitted light image by the excitation image to generate a normalized emitted light image of the tissue.
