Figure 4

Illustration of the registration links between the images that the SRI24 atlas is constructed from. For each subject, the b = 0 EPI is registered to the late‐echo FSE image, which in turn is registered to the SPGR image. The early‐ and late‐echo FSE images from each subject were acquired in a single, dual‐echo acquisition and are, therefore, in perfect registration. The SPGR images from all 24 subjects are coregistered using a simultaneous, template‐free registration algorithm.
