ASTRA-Net 模型在标注数据有限的情况下改进了 DISE 分割

研究人员开发了 ASTRA-Net,一个专为药物诱导睡眠内窥镜 (DISE) 图像分割设计的新颖系统,尤其适用于真实标注数据稀缺的情况。该系统采用两阶段方法:首先,使用 ConvNeXt-Base 将来自大量未标记虚拟内窥镜帧的大型数据集的中间表示与真实的 DISE 帧对齐。其次,在有限的 401 个真实标注帧上微调四个独立的 UNet++ 解码器。该方法在保留的评估集上实现了 0.8927 的平均 Dice 分数和 0.8239 的平均交并比,证明了其在标注数据有限的情况下描绘气道边界的有效性。 AI

影响 在标注数据有限的情况下,能够实现更准确的医学图像分析。

    ASTRA-Net:用于药物诱导睡眠内窥镜分割的解剖结构特定迁移与表示对齐

    arXiv:2607.21370v1 Announce Type: new Abstract: Quantitative drug-induced sleep endoscopy (DISE) requires reliable airway boundaries at specific anatomical levels. Pixel-level DISE annotations are scarce, and manual contouring limits the scalability of quantitative assessment. To…
