Simulation of thermal reaction of biological tissues to laser-induced fluorescence and photodynamic
therapy
A Seteikin and I Krasnikov
Amur State University, Russia
The aim of this work was to evaluate the temperature fields and the dynamics of heat conduction into the skin tissue under several
laser irradiation conditions with both a pulsed ultraviolet (UV) laser (λ=337 nm) and a continuous-wave (cw) visible laser
beam (λ=632.8 nm) using Monte Carlo modeling. Finite-element methodology was used for heat transfer simulation. The analysis
of the results showed that heat is not localized on the surface, but is collected inside the tissue in lower skin layers. The simulation
was made with the pulsed UV laser beam (used as excitation source in laser-induced fluorescence) and the cw visible laser (used in
photodynamic therapy treatments), in order to study the possible thermal effects.
