Symmetry plane of the brain on perfusion MR images

In this paper we present algorithm which purpose is to estimate real symmetry plane of the brain on the MRI perfusion studies. Because perfusion slices are acquired in low resolution and larger distances, than standard MRstudies, symmetry plane of the brain must be evaluated on the slice-by-slice basis. Presented algorithm therefore searches for symmetry line taking into consideration only anatomical information on each slice, ignoring adjacent slices. After presenting the method and sample results, we present results of tests. © 2010 Springer-Verlag Berlin Heidelberg.
