Effective Exploitation of Prior Information in Electrical Impedance Tomography for Thermal Monitoring of Hyperthermia Treatments

Real-time monitoring of hyperthermia treatments for liver cancers by noninvasive techniques was investigated in the last two decades. Among the proposed techniques, Electrical Impedance Tomography (EIT) arises particular interest for its low cost and sensitivity to tissues parameter changes to be detected. In this paper, an approach based on the intensive but critical exploitation of prior information is proposed and a preconditioning method of the impedance measurements based on a sensitivity analysis is assessed.
