MARIE (MAgnetic Resonance Integral Equation suite) is an
open-source software for fast EM analysis of MRI
systems. It combines surface and volume integral
equation formulations to exploit the characteristics of
the different parts (coil array and body model), and
applies sophisticated numerical methods to rapidly
perform EM simulations to characterize the MRI design.
Running on a GPU-accelerated windows desktop, MARIE
solves complex scattering problems in ~2-3 min.,
port-parameter analysis of complex coils in ~3-5 min.
per frequency, and a complete inhomogeneous body and
coil system in ~5-10 min. per port. It includes a GUI
for standard simulations, and scripts to develop more
advanced analyses, such as ultimate intrinsic SNR/SAR on
body models, fast coil design and optimization, or
generation of patient specific protocols.
