1D Shimming:
Low S/N encountered. The acquisition parameters will be changed to improve this issue.
echo time must be reduced
Iteration 1: LSQ Before= 3.826 Hz, Target= 0.589 Hz, After= 1.712 Hz
Iteration 2: LSQ Before= 1.712 Hz, Target= 0.478 Hz, After= 0.957 Hz
Iteration 3: LSQ Before= 0.957 Hz, Target= 0.362 Hz, After= 3.794 Hz
echo time must be reduced
Iteration 4: LSQ Before= 3.794 Hz, Target= 1.015 Hz, After= 4.081 Hz
Iteration 5: LSQ Before= 4.081 Hz, Target= 1.003 Hz, After= 2.682 Hz
Iteration 6: LSQ Before= 2.682 Hz, Target= 1.165 Hz, After= 0.969 Hz
Iteration 7: LSQ Before= 0.969 Hz, Target= 0.701 Hz, After= 1.373 Hz
Iteration 8: LSQ Before= 1.373 Hz, Target= 0.350 Hz, After= 2.366 Hz
Using the best result as the final shim state.
