This research aims to develop a probabilistic atlas to detect deviations in normal brain structure in 3D MRI images.
A comprehensive probabilistic atlas of the cerebral cortex was devised using high-dimensional fluid transformations.
3D MR images were processed to extract high-resolution cortical surfaces and calculate volumetric maps for anatomical correspondence.
A probability space using Gaussian random fields was created to encode anatomical variations between subjects.
Color-coded probability maps demonstrated patterns of anatomical deviation in new subjects' brains.
The atlas analyzed 3D MRI volumes from subjects with clinically confirmed Alzheimer disease compared to age-matched controls.
Probability maps indicated the likelihood of local anatomical points being unusually positioned based on normal distribution patterns.
