Classic Sequential Ordering

Use the Classic Sequential Ordering User CV with VIBRANT Gradient Echo PSD. The User CV refers to k-space filling technique. The VIBRANT k-space filling technique fills k-space linearly from 1-n and places the center of k-space at exactly half the phase encoding steps. This technique can reduce ring-like image artifacts. There are two options:

  • 0 = Off the default state.
  • 1 = On and k-space will be filled in a linear order as well but with the center of k-space not exactly at N/2 phase encoding steps.
