Basic description of Diffusion Weighted Image (DWI) data
Objects can be created by calls of the form new("dti", ...)
.
.Data
:"list"
usually empty btb
:"matrix"
matrix of dimension c(6,ngrad)
obtained from gradient directions.ngrad
:"integer"
number of gradients (including zero gradients) s0ind
:"integer"
index of zero gradients within sequence 1:ngrad
replind
:"integer"
index (identifier) of unique
gradient directions. Used to charactreize replications in the gradient design by identical indices. length is ngrad
ddim
:"integer"
dimension of original image cubes. Integer vector of length 3. ddim0
:"integer"
dimension of subcube defined by xind
, yind
and zind
. xind
:"integer"
index for subcube definition in x-direction yind
:"integer"
index for subcube definition in y-direction zind
:"integer"
index for subcube definition in z-direction voxelext
:"numeric"
voxel extensions in x-, y- and z-direction. vector of length 3. source
