Abstract
A method of selective excitation of a first spectral band in the presence of a second spectral band whose magnetization vector is not to be affected, comprising: selecting a central synthesizer frequency of substantially the second spectral band; applying a spectral-spatial pulse, centered on the selected synthesizer frequency to selectively excite the first spectral band. Preferably, the spectral-spatial pulse is a type II spectral-spatial pulse having odd and even pulse trains.

A method of selective excitation of a first spectral band in the presence of a second spectral band whose magnetization vector is not to be affected, comprising:
- selecting a central synthesizer frequency of substantially the second spectral band;
- applying a spectral-spatial pulse, centered on the selected synthesizer frequency to selectively excite the first spectral band.
A method of affecting magnetization vectors in magnetic resonance, comprising:
- providing a type II spectral-spatial pulse having odd and even magnetization lobes;
- and
- modifying at least one parameter of said pulse to independently control a characteristic of said odd lobes with respect to said even magnetization lobes, wherein said at least one parameters includes at least one relative phase shift of between at least two individual sub-pulses of said pulse, and wherein modifying comprises modifying said at least one parameter to reduce the amplitude of a particular magnetization lobe.
