Impedence Method for Calculation of Power Deposition Patterns in Magnetically Induced Hyperthermia

To obtain a detailed view of the power deposition pattern resulting from time-varying magnetic fields used in hyperthermia, we have developed a method of modeling portions of the human body using an impedance network. The region of interest is subdivided into a number of cells, each of which is then replaced by an equivalent impedance, and the currents induced in the resulting network due to the prescribed magnetic field are found by the application of circuit theory.
