Results:


1D Shimming:
Low S/N encountered. The acquisition parameters will be changed to improve this issue.
Iteration  1: FWHM Before= 1.3 Hz, Target= 0.2 Hz, After= 0.4 Hz
Iteration  2: FWHM Before= 0.4 Hz, Target= 0.3 Hz, After= 0.4 Hz
Iteration  3: FWHM Before= 0.4 Hz, Target= 0.3 Hz, After= 0.4 Hz
Iteration  4: FWHM Before= 0.4 Hz, Target= 0.2 Hz, After= 0.4 Hz
Iteration  5: FWHM Before= 0.4 Hz, Target= 0.2 Hz, After= 0.5 Hz
Iteration  6: FWHM Before= 0.5 Hz, Target= 0.4 Hz, After= 0.7 Hz
Using the best result as the final shim state.
