Abstract
An important goal to achieve in order to improve the clinical usefulness of regional cerebral blood flow (rCBF) SPECT studies is to register each brain to a standard anatomical atlas. For this purpose, we propose a simple three steps method. First the mid-sagittal plane is computed based on the left-right symmetry of the brain. Then the AC- PC line (main axis of the Talairach & Tournoux reference system) is obtained from the positions of four landmarks in the mid-sagittal plane. Finally, three linear scaling parameters are determined to adjust the size of the subject brain within the Talairach & Tournoux Atlas. The method was successfully validated with a set of 64 X 64 X 64 SPECT Monte-Carlo simulations of the brain.
