Correction for Rician Bias assuming known variance parameter
# S4 method for dtiData
dwiRiceBias(object, sigma=NULL, ncoils=1)
An object of class "dtiData"
.
Object of class "dtiData"
Scale parameter that relates the distribution of the signal to a \(\chi_{2L}\) distribution
number of effective coils in parallel imaging, the related \(\chi\)
distribution has 2*ncoils
degrees of freedom.
Returns a warning.
Returns a dtiData
object with bias-corrected image intensities.
