A novel 8Tx/16Rx coil array was designed, simulated, and tested in phantom and for cardiac magnetic resonance imaging (cMRI) ex-vivo pigs at 7T. The 16-elements of the array were distributed on a half-elliptical shape housing. Combined signal-to-noise ratio (SNR) maps and FA-maps were acquired using the developed coil before and after RF-shimming. The novel cardiac array supports parallel imaging with acceleration factors of up to R=4 without a significant degradation in the image quality. High-resolution ex-vivo cardiac images were acquired with 0.3mm x 0.3mm in plane resolution. The dedicated coil enhances the SNR within the heart by about six-times compared to a commercial human cardiac coil array.
