The feasibility of simultaneous
transmit/receive was studied at 1MHz. This study demonstrates survival of the NMR
signal in nanovolt level in strong radio frequency
interference.
Figure 1. (a) The
open MRI system. (b) The diagram of simultaneous transmit and receive. The phantom is above the
coils. The coil on the right side is for the use of picking up NMR signal at
1MHz, and the coil on the right side is irradiating offset field.
Figure 5. Experiments for simultaneous transmit and
receive. (a) The diagram of a multiple spin echo sequence with continuous
offset irradiation in the front five acquisition window. (b) Experimental data acquired
with the sequence above with echo spacing (TE) 1ms. It shows three echo trains
under different offset-field irradiations.
