Purpose

The module TensorTestPattern creates simple DTI image with phantom data.

Details

The output pattern is generally made of 'tissue' and 'background' tensors.

The eigenvalues of these two kinds of tensors may be adjusted via the Tensor Ext. parameters. One may adjust the outer and inner radius parameters of the pattern modes. Tissue tensors will fill the space which has a distance to the center greater than inner radius and smaller than outer radius.

If the pattern mode is set to 'helical' one may additionally specify the amplitude and frequency of the helix.
