Full Definition
NIfTI (Neuroimaging Informatics Technology Initiative) is a file format designed to provide a simple, flexible way to store neuroimaging data. The format supports both single-file (.nii) and dual-file (.hdr/.img) configurations and includes comprehensive header information about image acquisition parameters, spatial orientation, and data scaling. NIfTI has become the de facto standard for sharing neuroimaging data across different software platforms.
