 We present the initial experience of using a commercial version of the 8Tx/16Rx thorax array operating in the pTX-Compatibility Mode of the scanner for cardiac MRI at 7T.       
 
Figure 2 Long and short-axis view of the heart acquired at different flip-angles with both arrays. A pronounced appearance of blood-flow induced artifacts is observed with the new array, probably due to lower B1-gradients in the anterior-posterior direction.
Figure 5 Result from optimized B1-vectors calculations. Panels (a) and (b) show the B1-field on the "Duke" model in the transversal and sagittal slices respectively. A sufficient penetration depth with better coverage of the posterior heart (lung and heart contours are shown) is predicted by these simulations for future measurements.
