dwiRiceBias-methods: Correction for Rician Bias

In WIAS-BERLIN/dti: Analysis of Diffusion Weighted Imaging (DWI) Data

Correction for Rician Bias

Description

Correction for Rician Bias assuming known variance parameter

Usage

  ## S4 method for signature 'dtiData'
dwiRiceBias(object, sigma=NULL, ncoils=1)

Arguments

object	Object of class "dtiData"
sigma	Scale parameter that relates the distribution of the signal to a \chi_{2L} distribution
ncoils	number of effective coils in parallel imaging, the related \chi distribution has 2*ncoils degrees of freedom.

Value

An object of class "dtiData".

Methods

object = "ANY"

Returns a warning.

object = "dtiData"

Returns a dtiData object with bias-corrected image intensities.
