Figure 7. Representative Results for a Diffusion-Weighted Image.

Figure 7

(A) A diffusion-weighted image in the original resolution; (B) The linearly up-sampled image; and (C) The up-sampled image generated with the help of the directional information borrowed from the diffusion-weighted data. Since the gradient direction for this example is approximately in the left-right direction, white matter structures with fibers running in the left-right direction should have a darker intensity (see for example the structure marked by the red arrow); white matter structures with fibers running in the anterior-posterior direction or superior-inferior direction should have brighter intensity (see for example the structure marked by the green arrow).
