Enhancing the Detection of BOLD Signal in fMRI by Reducing the Partial Volume Effect
Figure 10
A comparison of the original (a) and VSI interpolated (b) echo-planar images shows that VSI improves delineation between the gray and white matter. In order to show these two images in the same size, each voxel in the original image was duplicated by a factor of 4 to form a 128 × 128 image in (a). The edge of the brain also appears much smoother in the interpolated image than in the original image.
