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,
  ensure_odd = TRUE
)

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).
ensure_odd: add 1mm to the FOV when required to ensure the output pdf has odd dimensions. Required when using get_mrsi2d_seg.

Value

A matrix of the PSF with 1mm resolution.
