Background:

Accurate spatial alignment of functional magnetic resonance imaging (fMRI) data is crucial for group analysis in fMRI studies.
Traditional structural MRI-based registration methods struggle with inter-subject functional consistency due to inherent functional variability.
Spatial smoothing, while reducing variability, can blur fine-grained functional signals.

Purpose of the Study:

To develop a novel method for spatial normalization of fMRI data that enhances inter-subject functional consistency.
To overcome the limitations of existing fMRI registration techniques, particularly in preserving fine-grained functional information.

Main Methods:

Proposed a novel fMRI spatial normalization method by progressively matching multi-range functional connectivity patterns.
Image registration achieved by maximizing inter-subject similarity of local functional connectivity patterns for each voxel.
Employed a congealing groupwise image registration strategy to simultaneously warp a group of subjects to an unbiased template.

Main Results:

The proposed method demonstrated superior registration performance for resting-state fMRI data compared to existing methods.
Experimental results showed a statistically significant improvement in inter-subject functional consistency.
The method effectively captures functional connectivity information across gradually increasing spatial ranges.

Conclusions:

The novel fMRI registration method significantly improves inter-subject functional consistency.
This approach offers a more accurate way to normalize fMRI data for group analyses.
The technique preserves fine-grained functional information better than traditional methods.
