Abstract:

Light has long being used in medicine; however, the high scattering of biological tissues always hindered its use. The aim of this work is the development of methodologies to focus light inside biological tissues. Geant4/GAMOS Monte Carlo platform was used to simulate the possibility of parameterize the time delay of multiple sources of external light, offset in time, as a function of the interest region position in order to create constructive interferences in a breast sample. A computational model was implemented and the platform was configured in order to perform these simulations. Preliminary results using a single light source were performed. It was concluded that scattering in adipose tissue is very high which is consistent with previous studies.
