ABSTRACT:
A method, apparatus, and set of compositions are disclosed for calibrating a bio-photonic scanner. The scanner detects selected molecular structures of tissues, nondestructively, in vivo. The apparatus may include a computer, including processor and memory connecting to the scanner, including an illuminator to direct light nondestructively onto tissue in vivo, a detector to detect an intensity of a radiant response of the tissue to the light, and a probe to direct light onto the subject and receive a radiant response back into the detector. The apparatus is calibrated using a synthetic material to mimic the radiant response of live tissue, correcting for background fluorescence and elastic scattering. Dopants in a matrix of synthetic material mimic selected molecular structures of tissue. Matrix materials include a dilatant compound, and dopants include biological materials as well as K-type polarizing film powdered and mixed.
