Trajectory

Different 3D radial k-space trajectories for interleaved acquisitions

Trajectory Functions

Functions that can be used for reconstruction

pymerlin.trajectory.piccini_phyllotaxis	Generate a spiral phyllotaxis trajectory with square root z-modulation according to formulation by Piccini et al. Note, this does not give a uniform FOV but slightly higher sampling in the x/y plane than along z.
pymerlin.trajectory.swinbank_phyllotaxis	Generate a spiral phyllotaxis trajectory with cosine z-modulation for uniform spherical sampling.
pymerlin.trajectory.linear_phyllotaxis	Isotropic Phyllotaxis trajectory with linear interleave ordering and arbitrary smoothness factor
pymerlin.trajectory.wong_roos_traj	3D Radial trajectory as formulated by Wong and Roos
pymerlin.trajectory.wong_roos_interleaved_traj	Interleaved trajectory by Wong and Roos
pymerlin.trajectory.traj2points	Transform spoke trajectory to point trajectory
