Signal-to-noise ratio (SNR) in cardiac MRI (cMRI) is a parameter associated with the field strength, the parallel imaging (PI) acceleration factor and the geometry of receive array element arrangement (g-factor). The purpose of this work was to evaluate four different arrays with symmetrical and asymmetrical distribution of 16RX and 8TX elements ex-vivo in swine at 7T MRI. The asymmetrical design proved to be superior with regard to SNR and image homogeneity.
