Laser- tissue interaction principles: beam penetration in tissue

In this communication, we continue in analyzing the principles of laser-tissue interaction, by considering a more advanced model in which light scattering is taken into consideration. Scattering is one of the fundamental phenomena which is always present in the case of biomedical applications. After a brief introduction about the scattering of light and its physical modelling, we will consider how the presence of scattering modifies the laser penetration depth in tissues.
