摘要

膝关节前交叉韧带(ACL)损伤的精准影像评估对临床诊疗至关重要。针对ACL解剖结构细长、体积微小且背景组织复杂,导致传统深度学习模型难以兼顾全局依赖与局部细节的问题,本研究提出了一种基于SwinUNet-FPN的自动分割模型。该模型以纯Transformer架构的Swin-UNet为骨干,利用移动窗口自注意力机制提取全局特征,并引入特征金字塔网络(FPN)模块,通过横向连接融合深层语义与浅层细节信息。在KneeMRI数据集上的实验结果表明,该模型在Dice相似系数(DSC)和95%豪斯多夫距离(HD95)上分别达到0.812 7和18.234 5,显著优于U-Net、ResUNet及原始Swin-UNet模型。结果证实该方法能有效克服复杂背景下的分割难题,提升边缘识别精度,具有重要的临床辅助价值。
