Our Magnetic Resonance Integral Equation suite (MARIE) is a numerical software platform for comprehensive frequency-domain fast electromagnetic (EM) analysis of MRI systems. The tool is based on a combination of surface and volume integral equation formulations. It exploits the characteristics of the different parts of an MRI system (coil array, shield, and realistic body model), and it applies sophisticated numerical methods to rapidly perform all the required EM simulations to characterize the MRI design: computing the un-tuned coil port parameters, obtaining the current distribution for the tuned coils, and obtaining the corresponding electromagnetic field distribution in the inhomogeneous body for each transmit channel.
