Abstract :
Electrical impedance tomography and microwave imaging methods for monitoring the temperature distribution during hyperthermia treatment is discussed. The numerical models, primarily finite element based, are described for each with attention to the differences in the governing partial differential equations. The reconstruction algorithms for determining the tissue properties are discussed. Finally, preliminary results using electrical impedance tomography to map conductivity changes during hyperthermia are shown
