atlas registration
Process of aligning individual brain images to a standardized anatomical template or atlas.
Full Definition
Atlas registration is a fundamental preprocessing step in neuroimaging that involves spatially transforming individual brain images to align with a standardized brain template or atlas. This process enables comparison across subjects and studies by establishing correspondence between anatomical structures. Registration can be linear (affine) or non-linear (deformable) and is essential for group-level statistical analyses and automated anatomical labeling.
Usage
Usage note: Hyphenate when used as a compound term.
