Radial sampling patterns in frequency space to support anisotropic field of views (FOVs) in the dual domain
This archive includes Matlab functions to design acquisition schemes for radial fourier/frequency space sampling that will support the desired field-of-view (FOV), where the primary application is for MRI acquisition trajectories in k-space. Included are design functions for 2D and 3D radial frequency space sampling, as well as PROPELLER MRI trajectories and golden angle ordering. C implementations for designing elliptical FOV trajectories are also included.

Within Matlab, use "help Radial-Field-of-Views" for information on the design functions included in this package. Documentation on each specific function is also included.
