Synopsis of RF coil configurations used in this study.

<p><b>Top:</b> Photographs of the cardiac optimized 7.0 T transceiver RF coil arrays to illustrate the coil design and the coil geometry together with the coil positioning used in the UHF-CMR setting. The RF coils employed include a four channel [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0117095#pone.0117095.ref040" target="_blank">40</a>], an eight channel [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0117095#pone.0117095.ref041" target="_blank">41</a>], a 16 channel [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0117095#pone.0117095.ref009" target="_blank">9</a>,<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0117095#pone.0117095.ref042" target="_blank">42</a>] and a 32 channel loop coil [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0117095#pone.0117095.ref043" target="_blank">43</a>] configuration and an eight channel [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0117095#pone.0117095.ref044" target="_blank">44</a>] and 16 channel bow tie antenna array configuration [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0117095#pone.0117095.ref045" target="_blank">45</a>]. <b>Bottom:</b> Short axis views of the heart derived from 2D CINE FLASH acquisitions using the RF coil configurations in the top row and a spatial resolution of (1.4 x 1.4 x 4) mm³ and parallel imaging (R = 2, GRAPPA reconstruction).
