Determining distribution of chromophores in skin or other epithelial tissue

摘要

Apparatus for aiding diagnosis of skin disorder includes a hand-held device 103 containing LEDs 203 for illuminating the skin through an aperture 210, and means 213 for detecting light remitted from the skin at selected wavelengths corresponding to known chromophores. Variations in intensity of light emitted from points across lesions in the skin are measured, and the results are processed and interpreted by a microprocessor 205.
