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.
