The feasibiltiy of cardiac MRI at 7T using a transmit array was demonstrated. A software solution was implemented for synchronizing the independent array CPUs with the cardiac trigger and CINE images were acquired with a modified product sequence for cardiovascular imaging. Using the 7T system in Tx array or single channel mode with hardwired phase settings produced identical image quality. In this proof-of-principle study the Tx array was used for static B1 shimming only but the concept permits dynamic applications like transmit SENSE as well.
