MARIE (MAgnetic Resonance Integral Equation suite) is a MATLAB-based open source prototype software for frequency domain fast electromagnetic (EM) analysis of MRI systems. This analysis includes the full-wave EM simulation of the coil design in the presence of the human body. The goal is to compute the port parameters at the operational frequency, and the detailed EM field distribution in the inhomogeneous body, in order to obtain relevant figures of merit such as B1+, B1- and local SAR maps.

MARIE 2.0 was released in 2023, describing a compressed-perturbation-matrix technique that allows to substantially reduce simulation time.
