Implication

Computational evaluation demonstrates high anatomical accuracy when elastically matching a 3D atlas to MRI volumes, indicating improved alignment when incorporating gray-white interfaces.

Key Points

To evaluate the anatomical matching accuracy of a system designed to elastically deform a three-dimensional brain atlas onto magnetic resonance image volumes.
Generated six deformed atlas versions by elastically mapping an anatomical brain atlas onto different MR brain image volumes using brain surface and ventricular edge alignment.
Evaluated correspondence across 32 cortical and subcortical structures by matching the atlas back to its deformed variations, testing configurations with and without the gray-white interface.
Standard matching localized structure centroids within an average of 1 mm, fit volumes to within 11%, and yielded a mean intersection-over-union volume overlap of 66%.
Incorporating the gray-white interface improved mean overlap to 78%, structural centroid correspondence to within 0.6 mm, and volume fitting accuracy to within 6%.
