  • Publication number: 20240192298
    Abstract: According to a first aspect of the present inventive concept, there is provided a method for performing a diffusion weighted magnetic resonance measurement on a sample, the method comprising: operating a magnetic resonance scanner to apply a diffusion encoding sequence to the sample; and operating the magnetic resonance scanner to acquire from the sample one or more echo signals; wherein the diffusion encoding sequence comprises a diffusion encoding time-dependent magnetic field gradient g(t) with non-zero components gl(t) along at least two orthogonal directions y and z, and a b-tensor having at least two non-zero eigenvalues, the magnetic field gradient comprising a first and subsequent second encoding block, wherein an n-th order gradient moment magnitude along direction l?(y, z) is given by |Mnl(t)|=|?0tgl(t?)t?ndt?|, and the first encoding block is adapted to yield, at an end of the first encoding block: along said direction y, |Mny(t)|?Tn for each 0?n?m, where Tn is a predetermined n-th order thresh

  • Patent number: 11747423
    Abstract: Inventive technology is directed to diffusion weighted magnetic resonance measurements. In an embodiment, a method for performing a diffusion weighted magnetic resonance measurement on a sample includes operating a magnetic resonance scanner to apply a diffusion encoding sequence to the sample. The method also includes operating the magnetic resonance scanner to acquire from the sample one or more echo signals. The diffusion encoding sequence includes a diffusion encoding time-dependent magnetic field gradient g(t) with non-zero components gl(t) along at least two orthogonal directions y and z, and a b-tensor having at least two non-zero eigenvalues, the magnetic field gradient comprising a first and subsequent second encoding block.
