PHOTOACOUSTIC PROBE FOR BURN INJURY DIAGNOSIS

摘要

A method and apparatus for depth profiling the structure of a subsurface region of skin, in particular burned skin, wherein the method/apparatus comprises directing laser light at an absorbing target to generate ultrasonic sound waves, which are used to determine the sound speed in the skin, and using the determined sound speed in conjunction with two-wavelength photoacoustics to depth profile of the structure of the subsurface of the skin.
