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.
