Seeing the light
Biopsies may become
rare as photon migration imaging develops into a powerfull noninvasive
diagnostic tool.
NIR Tissue Interaction
Optics provides an inexpensive
and noninvasive means to monitor blood physiology and more. For example,
hold a flashlight to your finger; the red light is the only color transmitted.
Hemoglobin absorbs blue and green very strongly, but it absorbs red very
weakly.
