Most array coils used for body imaging utilize regular shaped rectangular or circular surface coils evenly distributed to cover the entire torso. The cardiac region comprises a relatively small volume compared to the entire human torso, therefore, an optimized cardiac array coil should reflect this, to make the best use of a limited number of receivers. Here, a 31-channel cardiac array was designed and constructed for focused performance within the cardiac region, providing improved SNR in addition to better g-factor performance. Up to 200% SNR gains and more aggressive reduction factors were achieved relative a 12-channel OEM cardiac array.
