dwiRiceBias-methods: Correction for Rician Bias

Description

Correction for Rician Bias assuming known variance parameter

Usage

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

Value

An object of class "dtiData".

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.

Methods

object = "ANY"

Returns a warning.

object = "dtiData"

Returns a dtiData object with bias-corrected image intensities.
