摘要:

自动医学图像分割技术有望加快病理诊断,从而提高患者护理效率。然而,医学图像通常具有复杂的纹理和结构,并且模型常因下采样而面临图像分辨率降低和信息丢失的问题。为解决这一问题,我们提出 HC-Mamba,这是一种基于现代状态空间模型 Mamba 的新型医学图像分割模型。具体而言,我们在 HC-Mamba 模型中引入空洞卷积技术,通过扩展卷积核的感受野,在不增加计算成本的情况下捕获更广泛范围的上下文信息。此外,HC-Mamba 模型采用深度可分离卷积,显著减少模型的参数量和计算量。通过结合空洞卷积和深度可分离卷积,HC-Mamba 能够以低得多的计算成本处理大规模医学图像数据,同时保持高水平性能。我们在包括器官分割和皮肤病变在内的分割任务上进行了全面实验,并在 Synapse、ISIC17 和 ISIC18 上开展大量实验,以证明 HC-Mamba 模型在医学图像分割中的潜力。实验结果表明,HC-Mamba 在所有这些数据集上均表现出具有竞争力的性能,从而证明了其在医学图像分割中的有效性和实用性。

英文摘要:

Automatic medical image segmentation technology has the potential to expedite pathological diagnoses, thereby enhancing the efficiency of patient care. However, medical images often have complex textures and structures, and the models often face the problem of reduced image resolution and information loss due to downsampling. To address this issue, we propose HC-Mamba, a new medical image segmentation model based on the modern state space model Mamba. Specifically, we introduce the technique of dilated convolution in the HC-Mamba model to capture a more extensive range of contextual information without increasing the computational cost by extending the perceptual field of the convolution kernel. In addition, the HC-Mamba model employs depthwise separable convolutions, significantly reducing the number of parameters and the computational power of the model. By combining dilated convolution and depthwise separable convolutions, HC-Mamba is able to process large-scale medical image data at a much lower computational cost while maintaining a high level of performance. We conduct comprehensive experiments on segmentation tasks including organ segmentation and skin lesion, and conduct extensive experiments on Synapse, ISIC17 and ISIC18 to demonstrate the potential of the HC-Mamba model in medical image segmentation. The experimental results show that HC-Mamba exhibits competitive performance on all these datasets, thereby proving its effectiveness and usefulness in medical image segmentation.
