Get the point spread function (PSF) for a 2D phase encoded MRSI scan.

get_2d_psf(FOV = 160, mat_size = 16, sampling = "circ", hamming = FALSE)

Arguments

FOV

field of view in mm.
mat_size

acquisition matrix size (not interpolated).
sampling

can be either "circ" for circular or "rect" for rectangular.
hamming

should Hamming k-space weighting be applied (default FALSE).

Value

A matrix of the PSF with 1mm resolution.
