## Chapter 13/Figure 15.jpg Back | Home | Next | 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.
