Figure 6. Simple scaling of AP dimension using AC-PC distance in MRI and atlas. The left image has no scaling, but is anchored on MidACPC. The right image has the AP scaling correction on this MNI Atlas over the MRI. This simple method is effective for basal ganglia targeting.

MNI = Montreal Neurological Institute; AC = Anterior Commissure; PC = Posterior Commissure; MRI = Magnetic Resonance Imaging; AP = Antero-Posterior; MidACPC = Middle of Anterior Commissure and Posterior Commissure

MNI Atlas = Montreal Neurological Institute Atlas, please refer to reference [19].
