Alternative Approaches to Magnetic Resonance-Based Electric Properties Tomography and Local Specific Absorption Rate Estimation

In this paper, three electric properties tomography techniques based on magnetic resonance are applied to a realistic 2-D model problem representing the waist of an adult man. The capability of the inverse methods to recover the actual distribution of the electric properties is discussed and compared. In addition, the possibility to extend the methods to the estimate of local specific absorption rate of the radio frequency field generated in a magnetic resonance imaging, data concerning safety issues, is considered and compared.
