novel gradient crusher optimization scheme published in mrm the mr science lab has published a novel algorithm referred to as dephasing optimization through coherence order pathway selection (dotcops) which designs crusher schemes for any magnetic resonance spectroscopy experiment and can be used for any metabolite of interest.
the crusher gradient after the 180° pulse destroys the fid (free induction decay: the decaying signal) the one before the 180° pulse is to balance the one after. zipper type artefacts may be seen in the absence of spoiler gradients because the rf pulses used are not perfect. further reading on this topic:

static crusher gradients were implemented on all three axes and set to provide 8π and 4π phase dispersion around the first and second refocusing rf pulses respectively. the orthogonal crushers were implemented as described in the theory section and provided identical phase dispersions as the static scheme.

a pulsed field gradient is a short timed pulse with spatial-dependent field intensity. any gradient is identified by four characteristics: axis strength shape and duration. pulsed field gradient (pfg) techniques are key to magnetic resonance imaging spatially selective spectroscopy and studies of diffusion via diffusion ordered nuclear magnetic resonance spectroscopy (dosy).
