In this work we present an 8-channel Tx/Rx array for 7
Tesla whole-body imaging which is situated between the
inner bore liner and the gradient coil similar to the
body coils in standard low-field systems. The array is
compared to a close-fitting array of similar elements,
and first images of a human volunteer are presented.
While transmit efficiency and SNR are reduced in
comparison to a close-fitting array, a larger
field-of-view in the z-direction is achieved.
