Abstract: A method of measuring a specific absorption rate (SAR) of a hip joint implant using magnetic resonance imaging (MRI), includes: arranging the hip joint implant in a human lower body-shaped phantom; arranging an electric field sensor around the hip joint implant; providing radio frequency (RF) energy according to an MRI sequence to the human phantom; and calculating the SAR of the hip joint implant from strength of an electric field measured by the electric field sensor.
