Enhanced medical image segmentation through hybrid attention and dynamic convolution networks

Medical image segmentation is crucial in numerous clinical applications. Nevertheless, accurately segmenting anatomical structures in medical images proves challenging. This difficulty arises from factors including the local volume effect, intensity inhomogeneity, and inter-object occlusion. To address these challenges, our paper introduces an innovative method for medical image segmentation. This approach integrates a hybrid attention mechanism(HCA) and dynamic convolutional(DConv) operations, aiming to elevate the overall segmentation performance. The HCA integrates channel attention and spatial attention to capture contextual correlations between channels and spatial locations. DConv, on the other hand, extends traditional convolution operators with learnable offsets to better accommodate geometric transformations, enabling the network to adapt to complex segmentation tasks. Integrating these two mechanisms into an end-to-end medical image segmentation framework enables the network to understand and process image information more comprehensively. Through experiments conducted on datasets consisting of MRI and CT scans, our methodology not only attains performance at the forefront but also surpasses prior techniques notably in segmentation accuracy. These outcomes present a viable means to enhance the precision of medical image segmentation and open up additional prospects for future advancements in the realm of medical imaging.
