摘要

针对动脉瘤分割中存在的几何结构复杂、边界模糊等难点,提出多模块融合网络(CREANet)。该网络利用基于曲率的谱分析点重组策略,增强几何特征的提取能力;再经过多级回顾式特征优化模块,保留多尺度细节并促进多维度空间信息流动;并引入边缘感知增强模块,通过显式预测边缘概率增强边界识别能力。在IntrA数据集上的结果表明,该网络在血管分割中的交并比达95.06%,在动脉瘤分割中达84.42%,其分类准确率达94.56%,均优于一些最先进的模型。此外,在ModelNet40和ShapeNetPart数据集上,其总体分类准确率达93.4%,平均交并比达84.7%,证明了方法的鲁棒性与通用性。该研究为动脉瘤的精准分割提供了有效方案,具有临床应用潜力。
