reformatting (MPR) that can be used for any 3D ren-
dering application. MPR enables one to extract any ar-
bitrary plane of image data from the 3D volume image
that has been defined as a 3D texture. Applications can
use this capability to produce a 3D-rendered image. For
instance, if the volume is sliced into stacks of slices
parallel to the viewing plane that are then blended back-
to-front (with respect to the viewing plane), the volume-
rendered image can be obtained. This process is also
known as depth composition. The alpha component and
Figure 6.6-9 3D reconstruction of brain fiber from diffusion tensor imaging. (Left) White matter tracts that form the corona radiata are
shown: corpus callosum (yellow), anterior talamic radiation (red), corticobalbar/cortiscospinal tract (green), optic radiation (blue). (Right)
Association of fibers and tracts in the limbic system is shown: cingulum (green), fimbria (red), superior (pink) and inferior (yellow) longitudinal
fasciculus, uncinate fasciculus (light blue), and inferior fronto-occipitial fasciculus (blue). (Images courtesy of Susumu Mori, R. Xue,
