We have evaluated the Atlas based image analysis using Large Deformation Diffeomorphic Metric Mapping (LDDMM) on DTI age specific group average brains that have been created from a large cohort (0-22 yrs) of subjects that were recruited as part of the NIH MRI Study of Normal Brain Development project. Our goal has been to understand the utility of the atlas based method in accurately handling and extracting diffusion values that are representative both of the underlying structure and normal development.
