Abstract

A major constraint in photomedicine is the scattering of photons within tissue, which can limit the penetration of light to reach target structures such as a tumor. Laser-induced shockwaves could offer a potential approach to mitigate this constraint by modifying the optical scattering properties of tissue and re-directing the light to targeted regions. Preliminary results in a skin phantom suggest that laser-induced shockwaves can alter optical characteristics of a turbid medium, and subsequently, induce changes in light propagation.
