Hadamard excitation sculpting.
An approach to Hadamard phase encoding and editing in an excitation sculpting experiment is presented. When band- and/or frequency-selective experiments are performed at more than one site using excitation sculpting, use of Hadamard excitation sculpting (HEX sculpting) will reduce the total measuring time to achieve a target S/N. The application of HEX sculpting is demonstrated using selective 1D and NOESY1D experiments.
