Description
Diffusion Tensor Imaging is often used to produce maps of the neural fibre bundles in the brain. These maps are collections of streamlines, each following the local fiber direction. These paths contain a wealth of information about the connective pathwaths between the areas in the brain. To use these scans in comparative studies the need arises to perform measurements on specific fibre bundles. This paper introduces a method of selecting a specific fibre bundle by using box-shaped filters .
The figure below shows how the Cingulum is selected in a full brain tractography. To select the fiber bundle, three boxes are used. Only the fibers that pass through all three boxes are considered to be part of the nerve bundle. These fibers are here shown in opaque colors. The white transparent fibers show the fibers that pass none of the boxes, while the colored transparent fibers pass through at least one box (each box has its own specific color).
