Electromagnetic analysis of an RF rectangular resonant cavity applicator for hyperthermic treatment using whole-body voxel human model of Japanese adult male

The numerical whole-body voxel human model (numerical model) developed by National Institute of Information and Communications Technology (NICT) was assumed and hyperthemic treatment using radio-frequency wave was investigated. We assumed 51 different human tissues and organs with 2-mm spatial resolution in the numerical model, inserted it into the resonant cavity applicator, and Maxwell´s equations were solved by FDTD method with variable mesh. We obtained the realistic energy patterns for a deep-seated tumor as compared to those obtained in our previous studies.
