Abstract

A simplified 2-D model which is an example of regional RF hyperthermia is presented. Human body is inside the wire with exciting current and the electromagnetic energy is concentrated within the tumor. The analyzed model is therefore a coupling of the electromagnetic field and the temperature field. Exciting current density in human body has been calculated using the finite element method, and then bioheat equation in timedepended nonstationary case has been resolved. At the and obtained results are presented.
