In this study we compare different ways of modelling
decoupling in parallel transmission MRI systems using EM
solver simulations. One method is to model the
individual transmit elements independently without
including any decoupling networks leading to an ideally
decoupled system. The other method involves using
circuit co-simulation to model the entire system fully
along with the decoupling networks. Here we compare the
fields produced between the two methods and their
estimates of SAR showing that they both give comparable
results.
