Patent ID: 6991644

Claim:
A method for treating an area of tissue, where the area of tissue includes a plurality of different sub-areas of tissue which have different characteristics: providing a plurality of light emitting devices optically coupled with the area of tissue, wherein the light emitting devices are configured into different regions, where different sub-areas of tissue having different characteristics correspond to different regions of light emitting diodes; sensing an amount of light reflected from each of the different sub-areas; driving a first region of the plurality of light emitting devices to output a first light treatment to a first sub-area of tissue, wherein the first light treatment is determined based on a first amount of light reflected from the first sub-area; and driving a second region of the plurality of light emitting devices to output a second light treatment to a second sub-area of tissue, wherein the second light treatment is determined based on a second amount of light reflected from the second sub-area of tissue.
