… slices for each k-space line through using a different phase modulated RF pulse for each
k-space line acquisition. For example, alternating the phase of every other k-space line’s …

… We address this by adding +ϕ/2 phase to even k y lines and -ϕ/2 phase to odd k y lines
before reconstruction. The key observation is that the phase error is the same in both the bottom …

… Both 3D and SMS acquisitions can be viewed as encoding data in 3D k-space rather than
2D k-space 39. This enables improvements in PI reconstruction, since data undersampling …

… With the standard slice-GRAPPA (Std-SG), the GRAPPA kernels are calculated by solving:(1)
arg min ki S i − A sc k i 2 where S i and k i are vectors of k-space signal and GRAPPA …

… each k-space line. For example if alternating 180 phase shifts are applied to successive k y
lines … diffusion imaging applications since only a single RF pulse is employed for all k y lines. …

… add to the linear encoding gradients and create k-space shifts that vary in space and time. …
Image reconstruction techniques will be implemented that can model spatially dependent k-…

… The slice-selective trajectory consisted of several spokes in k z , separated in (k x ,k y ) with
spacing that corresponds to an FOV of 18 cm. Two versions of these trajectories (one with …

… This is to be expected, because the spokes trajectory, which is just a few delta points in k
x -k y , allows for much less control of the in-plane excitation profile when compared with the …

… (k x , k y ) for these simple designs to maintain them within a regime compatible with the
linear class of large tip angle pulses proposed by Pauly et al. (31) and used for parallel Tx work …

Purpose To develop an efficient acquisition for high‐resolution diffusion imaging and allow
in vivo whole‐brain acquisitions at 600‐ to 700‐μm isotropic resolution. Methods We …
