comb_coils_svs_gls: Combine SVS coil data using the GLS method presented by An et al JMRI 37:1445-1450 (2013).

Description

Combine SVS coil data using the GLS method presented by An et al JMRI 37:1445-1450 (2013).

Usage

comb_coils_svs_gls(
  metab,
  ref = NULL,
  noise_pts = 256,
  noise_mrs = NULL,
  use_mean_sens = TRUE,
  use_ref_sens = FALSE,
  change_order = NULL,
  no_noise_corr = FALSE,
  bc_poly_noise = 2
)

Value

coil combined MRS data.

Arguments

metab

MRS data containing metabolite data.

ref

MRS data containing reference data (optional).

noise_pts

number of points from the end of the FIDs to use for noise covariance estimation.

noise_mrs

MRS data containing noise information for each coil.

use_mean_sens

use the dynamic mean to estimate coil sensitivities.

use_ref_sens

use the reference data to estimate coil sensitivities.

change_order

change the order of the noise matrix reshaping, for testing purposes only.

no_noise_corr

assume noise is uncorrelated between coils, for testing purposes only. Defaults to FALSE.

bc_poly_noise

baseline correct the noise samples with a polynomial in the time-domain. Defaults to 2, which performs a second-order polynomial correction. Set to NULL to disable.
