Improvements in signal-to-noise-ratio (SNR)and B
of the TX/RX array configurations hold the promise to
increase the spatial resolution, which is promising in
order to gain better insight into myocardial
microstructures. For this reason this work investigates
the capabilities of a 16 channel cardiac array for
sub-millimeter spatial resolution of the heart at 7.0 T.
For this purpose numerical field simulations are
performed. A phase setting is derived to afford uniform
and efficient excitation. 2D CINE FLASH imaging of the
heart is performed in healthy subject using spatial
resolutions up to (0.8x0.8x2.5)mm
results of this work demonstrated that high resolution
CINE imaging of the heart at 7.0 T is feasible.
