Comparison between two approaches for the fiber tracking. In this example,
an ROI delineated the genu of the corpus callosum, which included 21 pixels.
In (A), tracking was initiated from the 21 pixels, resulting in 21 lines
to reveal the callosal connections between the frontal lobes. In (B), tracking
was initiated from all pixels in the brain and tracking results that penetrated
the ROI were searched. This approach resulted in identifying 1880 pixels
that were connected to the ROI, thus, revealing more comprehensive structure
of the callosal connections. |
