MRI phantoms for system tests or coil design should behave electrically similar to the patient, and thus, should be made of materials which have similar electric properties. In this study, a resonant probe was built up for the determination of electric conductivity and permittivity of phantom liquids. It is based on a measurement of resonance frequency and quality factor, which makes it more exact than standard direct methods.
