Preamplifier decoupling is a standard way of suppressing inter-element inductive coupling in MRI receive arrays. A well-known method to evaluate and optimize RF coils before practical fabrication is to use circuit-level and electromagnetic (EM) field-level simulations. However, to be best of our knowledge, currently there is not a solid method to evaluate the preamp decoupling effect with circuitry and EM field analysis. In this work, we used RF circuit and EM co-simulation4 to evaluate the preamplifier decoupling effect and tested it on the conventional coil (LIC) and the recently introduced high impedance coil (HIC).
