Most of the Magnetic Resonance Imaging studies require accurate knowledge of electrical properties of the phantoms. There are several techniques for measuring electrical properties of phantoms but there is lack of accuracy analysis. A new method to measure electrical properties of gel phantom was proposed based on the lead tip heating phenomena and used for verification of home made coaxial transmission line measurement fixture. Electrical properties of 3 different gel phantoms were measured using both methods and results are compared. Although the proposed method requires long MRI experiment, it can be used for verification of other electrical properties measurement techniques.
