Abstract: (51 Views) |
This study numerically investigates and compares the effectiveness of two thermal therapy techniques: radio frequency heating and microwave heating for the treatment of prostate tumors. Due to the lack of comprehensive numerical investigations in this field, the main objective is to evaluate the temperature distribution and the extent of tissue necrosis caused by each method. In this research, the geometry of the prostate was modeled in three dimensions for the radio frequency method and as a two-dimensional axisymmetric structure for the microwave method. In the radio frequency simulation, an electrical voltage of eight volts was applied for ten minutes, whereas in the microwave simulation, a frequency of 2.45 gigahertz and a power input of ten watts were used. The results show that both methods are effective in inducing tissue necrosis; however, microwave heating produced a more uniform temperature distribution and a broader area of necrosis. Moreover, microwave heating caused less damage to surrounding healthy tissue. Therefore, microwave thermal therapy may serve as a more efficient and safer approach for the localized treatment of prostate tumors. The findings of this study can support the optimization and selection of appropriate thermal treatment strategies in clinical oncology. |
