A dedicated 8Tx/16Rx coil array was designed and tested for cardiac magnetic resonance imaging (cMRI) ex-vivo pigs at 7T. The cardiac array is composed of 16-elements with physically independent anterior and posterior parts. The anterior array is composed of 8-elements and resembles a symmetric circular shape coil. The central four-elements are decoupled using a common central ring and shared decoupling capacitors. The posterior array was built using 4×2 rectangular symmetric elements configuration. Ex-vivo high-resolution cardiac images were acquired with 0.3 mm x 0.3 mm in plane resolution. The dedicated coil enhances the SNR within the heart by about four-times compared to a commercial human coil.
