ABSTRACT:
Systems, methods, and other embodiments associated with controlling the specific absorption rate (SAR) in a patient associated with a conductor are described. The conductor may be, for example, a wire associated with a pacemaker, a wire associated with a neurostimulator, an orthopaedic device, and so on. One example method includes calibrating a multi-channel transmitter associated with a magnetic resonance imaging (MRI) apparatus imaging the patient. The example method also includes controlling the MRI apparatus to transmit radio frequency (RF) energy to image the patient in a manner where the RF energy will only influence the SAR near the conductor in the patient less than a desired threshold amount.
