Regional cerebral blood flow in children with attention deficit hyperactivity disorder: comparison before and after methylphenidate treatment.

abstract：:Estimating the thickness of the cerebral cortex is a key step in many brain imaging studies, revealing valuable information on development or disease progression. In this work, we present a framework for measuring the cortical thickness, based on minimizing line integrals over the probability map of the gray matter in...
