Computing 10g averaged local SAR Q-matrices for parallel transmission MRI using self-implemented code is complex and computationally expensive. Here we present a simple method for computing Q-matrices using channel combinations of 10g SAR calculated with electromagnetic field simulation software and then simply constructed into Q-matrices from these combinations.
