Claim Text:
1. A method for acquiring magnetic resonance (MR) imaging data, comprising: operating a magnetic resonance data acquisition unit, with an examination subject therein, with an imaging data acquisition sequence comprising multiple preparation modules and at least one imaging module, with each of said multiple preparation modules preparing a magnetization of nuclear spins in the examination subject and wherein magnetic resonance signals, originating from said nuclear spins, are acquired in said at least one imaging module; in the respective multiple preparation modules, generating spoiler gradient magnetic fields that produce a transverse magnetization of said nuclear spins in the examination subject, with a spoiler gradient magnetic field generated in one of said preparation modules being spatially variable along a first spatial direction among three orthogonal spatial directions, and, in another of said preparation modules, generating a spoiler gradient magnetic field that is spatially variable along a direction among three orthogonal spatial directions that is different from said first spatial direction; generating said spoiler gradient magnetic fields with respective spoiler gradient moments that cause, for at least one of said three orthogonal spatial directions, a weighted sum of the spoiler gradient moments along said at least one of said three orthogonal spatial directions to satisfy a threshold condition; and entering said acquired magnetic resonance signals into a data file, and making said data file available in electronic form.
