Abstract:

Deformable registration plays a significant role in multiple medical image analysis tasks. However, the fixed receptive field of convolutional neural networks makes it difficult to fully capture the spatial context information of the brain. While the Transformer architecture can effectively capture global information, it suffers from high computational cost. To address this dilemma, we propose a deformable registration network based on multi-scale dilated residual convolution and dual attention. This network employs a multi-scale dilated residual convolution to capture local details and extensive context information simultaneously. A dual attention module is integrated to enhance feature representation capability. The decoder section introduces dynamic upsampling to precisely reconstruct high-frequency details, thereby ensuring the topological integrity of the deformation field. Experiments were conducted on two public brain datasets. The results demonstrate that the proposed model achieves high registration performance across multiple metrics, including Dice similarity coefficient (DSC), 95% Hausdorff distance (HD95), and percentage of non-positive Jacobian determinant, indicating superior registration precision and smoother deformation fields.
