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 ngradddim:"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:"character" name of the imgfile used to create the data. signature(x = "dti"): not yet implemented signature(object = "dti"): not yet implemented Karsten Tabelow tabelow@wias-berlin.de, J"org Polzehl polzehl@wias-berlin.de
