Temperature Variations in Biological Tissues Due to Spatial Dependent Blood Perfusion During Microwave Heating

The spatial dependent blood perfusion is modelled into the Pennes bio-heat equation and solved in conjunction with the Maxwell equation. The non-linear coupled equation is solved using a converging series expansion method. The converging series is invoked by the location of the electric field shock. Appropriate matching condition was introduced at selected matching point. The result agrees with literature on the role of blood perfusion. As blood perfusion increases in some location, the temperature increase while in some others it decreases. The effects of other tissue parameters in relation to the blood perfusion under the effect of the electric field were discussed. Adequate knowledge of the tissue location, physiological and thermo physical properties are to be known for an effective therapy to be performed.
