摘要:

乳腺X线检查是早期发现乳腺癌肿块最有效的影像学检查方法。来自两个成对视图的信息(即,内外斜位和头尾位)之间的关系是高度相关和互补的,这对于医生在临床实践中的决策至关重要。然而,现有的质量检测方法不考虑联合学习有效的功能,从两个关系的观点。为了解决这个问题,本文提出了一种新的乳腺肿块检测框架,称为基于交叉视图关系区域的卷积神经网络(CVR-RCNN)。所提出的CVR-RCNN有望从两个成对视图中捕获相应的质量感兴趣区域(ROI)之间的潜在关系信息。在一个新的大规模私人数据集和一个公共乳房X光检查数据集上的评估表明,所提出的CVR-RCNN优于现有的最先进的质量检测方法。同时,我们的实验结果表明,将跨两个视图的关系信息有助于训练一个更好的检测模型,这是一个有前途的途径,乳腺肿块检测。

英文摘要:

Mammogram is the most effective imaging modality for the mass lesion detection of breast cancer at the early stage. The information from the two paired views (i.e., medio-lateral oblique and cranio-caudal) are highly relational and complementary, and this is crucial for doctors' decisions in clinical practice. However, existing mass detection methods do not consider jointly learning effective features from the two relational views. To address this issue, this paper proposes a novel mammogram mass detection framework, termed Cross-View Relation Region-based Convolutional Neural Networks (CVR-RCNN). The proposed CVR-RCNN is expected to capture the latent relation information between the corresponding mass region of interests (ROIs) from the two paired views. Evaluations on a new large-scale private dataset and a public mammogram dataset show that the proposed CVR-RCNN outperforms existing state-of-the-art mass detection methods. Meanwhile, our experimental results suggest that incorporating the relation information across two views helps to train a superior detection model, which is a promising avenue for mammogram mass detection.
