This is the
first demonstration of in vivo human MR imaging with simultaneous transmit and
receive using continuous mode SWIFT at 4T. Due
to a large RF power difference between Tx and Rx working at the same frequency,
the difficulties to obtain the high and stable Tx/Rx isolation, and the
sensitivity of the Tx/Rx isolation to the loading conditions, in vivo images using the simultaneous RF
pulse transmission and signal acquisition have not been reported. This work
proposed the simultaneous Tx/Rx system with highly minimized effects from
variation of coil loading, which allowed us to acquire the first in vivo images with continuous SWIFT at
4T.
