Abstract

Issues of coagulation control were considered by simulating a controlled surface temperature irradiation using thermal feedback to execute an appropriate temporal proffle for laser power. In order to maintain a relatively 'constant' temperature at the surface of the tissue, a nonuniform pulse sequence would be required. 'Constant' surface temperature irradiation avoids high temperature effects, achieves relatively slow, steady progression of damage, allowing potential real-Time monitoring and control of coagulation front position. Furthermore, the difference in damage depth prediction using a constant property model as compared with a temperature dependent optical property model is much less for a 'constant' surface temperature irradiation than for a free running laser irradiation.
