Modeling of tissue heating with a pulsed Nd:YAG laser.
Temperature profiles were measured in large sections of bovine muscle and bovine liver exposed to single pulses from a clinical Nd:YAG laser. The data were analyzed with a photothermal model applicable to an incident gaussian beam including the effects of beam spread and heat flow. Closed form expressions for the radial average initial temperatures and thermal relaxation were derived and compared with the measurements.
