Multimodal Image Coregistration and Partitioning—A Unified Framework
John Ashburner,Karl J. Friston +1 more
TL;DR: The basic idea is that instead of matching two images directly, one performs intermediate within-modality registrations to two template images that are already in register, and a least-squares minimization is used to determine the affine transformations that map between the templates and the images.

How is the fusiform gyrus related to category-specificity?
TL;DR: It is demonstrated that category effects in the fusiform areas are stronger for pictures of objects than their written names, and that the posterior areas which are moreactive for animals than tools are also more active for fruits than tools.
Elastic registration in the presence of intensity variations
Senthil Periaswamy,Hany Farid +1 more
TL;DR: A general-purpose registration algorithm for medical images and volumes that models the transformation between images as locally affine but globally smooth, and is highly effective across a broad range of synthetic and clinical medical images.
Morphology enabled dipole inversion (MEDI) from a single‐angle acquisition: Comparison with COSMOS in human brain imaging
Tian Liu,Jing Liu,Ludovic de Rochefort,Ludovic de Rochefort,Pascal Spincemaille,Ildar Khalidov,James Robert Ledoux,Yi Wang +7 more
TL;DR: This study further improved the original MEDI method by sparsifying the edges in the quantitative susceptibility map that do not have a corresponding edge in the magnitude image, which shows a high degree of agreement between MEDI and calculation of susceptibility through multiple orientation sampling.
Functional MRI of macaque monkeys performing a cognitive set-shifting task.
TL;DR: Transient activation related to cognitive set shifting in focal regions of prefrontal cortex in both monkeys and humans is found in functional magnetic resonance imaging.
Category-related activation for written words in the posterior fusiform is task specific.
TL;DR: The results suggest that category-related activation in the posterior fusiform gyri can be driven either "bottom-up" by visual processing of images or "top-down" by word processing.

Spatial registration and normalization of images
Karl J. Friston,John Ashburner,Chris D. Frith,Jean-Baptiste Poline,Jon D. Heather,Richard S. J. Frackowiak +5 more
TL;DR: A general technique that facilitates nonlinear spatial (stereotactic) normalization and image realignment is presented that minimizes the sum of squares between two images following non linear spatial deformations and transformations of the voxel (intensity) values.

Rapid automated algorithm for aligning and reslicing PET images.
TL;DR: A computer algorithm for the three-dimensional alignment of PET images is described that relies on anatomic information in the images rather than on external fiducial markers and can be applied retrospectively, during acquisition, to reposition the scanner gantry and bed to match an earlier study.

TL;DR: The authors have collected over 300 MRI volumetric datasets from normal individuals and transformed these datasets into stereotaxic space using a 3D linear re-sampling algorithm, and generated a series of statistical measures which express this population nonlinear variability in the form of parametric volumes.

TL;DR: The results indicate that retrospective techniques have the potential to produce satisfactory results much of the time, but that visual inspection is necessary to guard against large errors.
