In this study, an implicit reference group-wise (IRG) registration with a small deformation,
linear elastic model was used to jointly estimate correspondences between a set of MRI …

This paper presents a set of validation procedures for nonrigid registration of functional EPI
to anatomical MRI brain images. Although various registration techniques have been …

Lack of tissue contrast and existing inhomogeneous bias fields from multi-channel coils
have the potential to degrade the output of registration algorithms; and consequently …

A comparative study of three inter-subject brain image registration methods (SPM99, AFNI,
and ART) is presented. It is shown that ART, which has a greater degree of freedom than …

Spatial alignment of functional magnetic resonance images (fMRI) of different subjects is a
necessary precursor to improve functional consistency across subjects for group analysis in …

Multiresolution strategies are commonly used in the nonrigid registration to avoid local
minima in the optimization space. Generally, a step-by-step hierarchical approach is …

We present a graph-cuts based method for non-rigid medical image registration on brain
magnetic resonance images. In this paper, the non-rigid medical image registration problem …

The non-rigid registration of a group of images shares a common feature with building a
model of a group of images: a dense, consistent correspondence across the group. Image …

Purpose Accurate deformable image registration is necessary for longitudinal studies. The
error associated with commercial systems has been evaluated using computed tomography …

In this work, we propose a new approach for three-dimensional registration of MR fractional
anisotropy images with T1-weighted anatomy images of human brain. From the clinical point …
