Parameter optimization of temperature field in RF-capacitive hyperthermia

摘要

To realize a certain target temperature distribution in tumor tissues ad avoid over-heating n normal tissues in radio frequency (RF)-capacitive hyperthermia, and objective function and some weight coefficients are intro- duced. Then using the 2-D finite element method, the electromagnetic and bio-heat transfer equations are solved, and using the genetic algorithm the heating configurations are recursively modified to minimize the objective function.
