Radial-Field-of-Views MATLAB package

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.
