摘要:

由于乳腺癌的高发病率和高死亡率,在乳房X线摄影中检测肿块具有重要意义。在乳房X线照片肿块检测中,明确地对成对病变对应进行建模是特别重要的。然而,大多数现有的方法建立相对粗糙的对应关系,并没有利用对应监督。在本文中,我们提出了一个新的基于transformer的框架CL-Net,以端到端的方式学习病变检测和成对对应。在CL-Net中,视图交互式病变检测器被提出来实现跨候选交叉视图的动态交互,而病变链接器采用对应监督来更准确地指导交互过程。这两种设计的组合实现了对乳腺X线照片的成对病变对应的精确理解。实验表明,CL-Net在公共DDSM数据集和我们的内部数据集上具有最先进的性能。此外,它优于以前的方法在低FPI制度的大幅度。

英文摘要:

Detecting mass in mammogram is significant due to the high occurrence and mortality of breast cancer. In mammogram mass detection, modeling pairwise lesion correspondence explicitly is particularly important. However, most of the existing methods build relatively coarse correspondence and have not utilized correspondence supervision. In this paper, we propose a new transformer-based framework CL-Net to learn lesion detection and pairwise correspondence in an end-to-end manner. In CL-Net, View-Interactive Lesion Detector is proposed to achieve dynamic interaction across candidates of cross views, while Lesion Linker employs the correspondence supervision to guide the interaction process more accurately. The combination of these two designs accomplishes precise understanding of pairwise lesion correspondence for mammograms. Experiments show that CL-Net yields state-of-the-art performance on the public DDSM dataset and our in-house dataset. Moreover, it outperforms previous methods by a large margin in low FPI regime.
