Özet:

 


This work compares the effect of a
monopole antenna without cooling unit on a biological tissue and a monopole
antenna with cooling unit. Computer simulation was done using a computer software
named COMSOL MultiphysicsTM, input power was varied from 10W to
120W, with an interval of 10W, at different times, from 60s to 120s at an
interval of 60s. It was observed that the diameter of
the lowest power (20W) decreased by -17.2% at 5mins, the length decreased by
-32.9% and aspect ratio for the two antennas increased by 23.40%. For medium
power (60W), at 5mins, the diameter decreased by -9.89%, length decreased by
-37.9%, and aspect ratio decreased by 45.24%. The p-value obtained from diameter
for low power showed no significant difference for ablation without water cool
(p > 0.005), but showed significant difference with water cool (p 
0.005 in both simulations, there was no statistically
significant difference in the diameter for high power (110W and 120W) for both
simulations, p-value > 0.005. The
result showed that inclusion of cooling unit reduced backward heating of
microwave antenna, ablation length, and ablation diameter of simulated tissue.
