Evaluation of atlas selection strategies for atlas-based image segmentation with application to confocal microscopy images of bee brains
TLDR
Segmentation by intensity-based nonrigid registration to atlas images is applied to confocal microscopy images acquired from the brains of bees. Expand

Volume-preserving nonrigid registration of MR breast images using free-form deformation with an incompressibility constraint
TLDR
In this paper, we extend a previously reported intensity-based nonrigid registration algorithm by using a novel regularization term to constrain the deformation, which is motivated by the assumption that soft tissue is incompressible. Expand

TLDR
The accuracy of nonrigid image registrations is commonly approximated using surrogate measures such as tissue label overlap scores, image similarity, image difference, or transformation inverse consistency error. Expand

Problem solving, working memory, and motor correlates of association and commissural fiber bundles in normal aging: A quantitative fiber tracking study
TLDR
We used quantitative fiber tracking to examine age effects on commissural (genu and splenium), bilateral association (cingulate, inferior longitudinal fasciculus and uncinate), and fornix fibers in 12 young and 12 elderly healthy men and women and tested functional correlates with concurrent assessment of a wide range of neuropsychological abilities.

Three‐dimensional average‐shape atlas of the honeybee brain and its applications
The anatomical substrates of neural nets are usually composed from reconstructions of neurons that were stained in different preparations. Realistic models of the structural relationships betweenExpand

Performance-based classifier combination in atlas-based image segmentation using expectation-maximization parameter estimation
TLDR
We propose two methods for performance-based combination of multiple classifiers and combine the individual classifiers by weighting them according to their estimated performance. Expand

MRI estimates of brain iron concentration in normal aging using quantitative susceptibility mapping
TLDR
We use recently-developed Quantitative Susceptibility Mapping (QSM) methodology to estimate the tissue magnetic susceptibility based on MRI signal phase, a sensitive measure of the tissue iron concentration, that gives rise to the observed signal phase. Expand

Variation in longitudinal trajectories of regional brain volumes of healthy men and women (ages 10 to 85years) measured with atlas-based parcellation of MRI
TLDR
We calculated trajectories of regional brain volume changes from T1-weighted (SPGR) MRI data, quantified with our automated, unsupervised SRI24 atlas-based registration and parcellation method. Expand
