Simulation-Based Model Thermal Ablation of Prostate Cancer Using High Intensity Focused Ultrasound
The use of High Intensity Focused Ultrasound (HIFU) in the medical treatment of cancer has attracted scientists and engineers with interest in achieving the most financially affordable but yet curative methods of curing different types of cancers. This present work considers a 2D modeling of the prostate gland without the environmental (neighbouring) tissues such as bladder, rectum, urethra and seminal vesicle. This model uses the nonlinear Westervelt equation since the propagation is in human tissue which is a nonlinear medium.Using a suitable application software (COMSOL) to solve the resulting equations, we predict the temperature distribution of the prostate when HIFU is applied. Our results are comparable to a similar work studied the acoustic streaming and convective cooling due to the use of HIFU.
