3-D temperature distribution in ultrasound hyperthermia with interstitial waveguide applicator.
Knowledge of temperature distribution in thermal treatment of cancerous tissue is of primary importance for the therapy success. We discuss here finite element analysis approach to obtain 3-D temperature distribution in heating with a four-applicator array. A comparison of phantom and simulation temperatures indicated that inclusion of shear component in heating with ultrasound interstitial applicators improves significantly the simulation quality factor. We included this component in simulations of 3-D temperature pattern when heating brain tissue with the array. The simulations for the tissue show that the perfusion remains a primary factor in defining the pattern.
