Background:

Pyramid-based encoder-decoder networks are popular for large deformation image registration.
Existing methods often overlook encoder impact and lack scale-specific feature map design.

Purpose of the Study:

To propose an innovative hybrid Transformer and convolution iteratively optimized pyramid network for large deformation brain image registration.
To address limitations in current registration models by optimizing feature encoders and decoder designs.

Main Methods:

Designed four encoder variants to assess their impact on registration performance.
Integrated Swin-Transformer modules with a convolution iterative strategy.
Tailored each decoder layer based on semantic information characteristics at different scales.

Main Results:

Achieved the highest registration accuracy across three public brain MRI datasets.
Outperformed 9 state-of-the-art registration methods in extensive experiments.

Conclusions:

The proposed hybrid network design demonstrates significant effectiveness for large deformation brain image registration.
The model shows strong potential for clinical applications in neuroimaging.
