• Abstract: Breast ultrasound videos contain richer information than ultrasound images, therefore it is more meaningful to develop video models for this diagnosis task. However, the collection of ultrasound video datasets is much harder. In this paper, we explore the feasibility of enhancing the performance of ultrasound video classification using the static image dataset. To this end, we propose KGA-Net and coherence loss. The KGA-Net adopts both video clips and static images to train the network. The coherence loss uses the feature centers generated by the static images to guide the frame attention in the video model. Our KGA-Net boosts the performance on the public BUSV dataset by a large margin. The visualization results of frame attention prove the explainability of our method. The codes and model weights of our method will be made publicly available.

  Ultrasound imaging serves as an effective and non-invasive diagnostic tool commonly employed in clinical examinations. Existing methods for speckle noise reduction induce excessive image smoothing or fail to preserve detailed information adequately. We propose a complementary global and local knowledge network for ultrasound denoising with fine-grained refinement.

  Region Attention Graph Networks (VRAG) improves the state-of-the-art video-level methods. VRAG represents videos at a finer granularity via region-level features and encodes video-temporal dynamics through region-level relations. We show that the performance gap between video-level and frame-level methods can be reduced by segmenting videos into shots and using shot embeddings for video retrieval.

  Several AI-based patient severity scoring models have been proposed that rely on scoring the appearance of the ultrasound scans. We address the challenge of labeling every ultrasound frame in the video clips. Our contrastive learning method treats the video clip severity labels as noisy weak severity labels for individual frames. We show that it performs better than the conventional cross-entropy loss based training.
