초록
The purpose of the study was to identify the effect of laser parameters on photocoagulation to maximizesafety and efficacy during varicose vein treatment. CW and pulsed modes at 1470 nm were initially compared as afunction of power on bovine liver tissue. In the pulsed mode, various parameters including repetition rate, duty cycle,and irradiation time were compared to evaluate tissue response during thermal treatment. The results demonstratedthat CW and pulsed modes yielded almost similar coagulation development possibly due to shorter irradiation timeof 5 sec. Regardless of laser mode, both repetition rate and duty cycle presented constant coagulation rate whereaslonger irradiation time facilitated coagulation process.
