Abstract

Coregistration of functional brain images across many subjects offers several experimental advantages and is widely used for studies in humans. Voxel-based coregistration methods require a high-quality 3-D template image, preferably one that corresponds to a published atlas. Template images are available for human, but we could not find an appropriate template for neuroimaging studies in baboon. Here we describe the formation of a T1-weighted structural MR template image and a PET blood flow template, derived from 9 and 7 baboons, respectively. Custom software aligns individual MR images to the MRI template; human supervision is needed only to initially estimate anygross rotational misalignment. In these aligned individual images, internal subcortical fiducial points correspond closely to a photomicrographic baboon atlas with an average error of 1.53 mm. Cortical test points showed a mean error of 1.99 min compared to the mean location for each point. Alignment of individual PET blood flow images directly to the PET template was compared to a two-step alignment process via each subject's MR image. The two transformations were identical within 0.41 mm, 0.54 degrees, and 1.0% (translation, rotation, and linear stretch; mean). These quantities provide a check on the validity of the alignment software as well as of the template images. The baboon structural AIR and blood flow PET templates are available on the Internet (purl.org/net/kbmd/b2k) and can be used as targets for any image registration software. (C) 2001 Academic Press.
