Synopsis of RF coil configurations used in this study. Top: Picture 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 coil employed include a four channel [1], an eight channel [2], a 16 channel [3, 4] and a 32 channel loop coil [5] configuration and an eight channel [6] and 16 channel bow tie antenna array configuration [7]. Bottom: 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).
