In cardiac imaging, parallel acquisition has impacted clinical applications to the point where nearly every cardiac examination is performed with an array comprising multiple smaller surface coil elements. In this study we re-design, construct, and evaluate a 64-channel cardiac array coil and compare it to a 34-ch commercially available coil array. We validated the arrays with SNR and g-factor maps and accelerated DWI in vivo imaging.
