DBF-Net: A Dual-Branch Network with Feature Fusion for Ultrasound Image Segmentation
This work addresses the problem of improving boundary quality in ultrasound image segmentation for medical applications, representing an incremental advancement over existing deep learning methods.
The paper tackles the challenge of accurately segmenting lesions in ultrasound images by introducing UBBS-Net, a dual-branch network that learns the relationship between body and boundary features, achieving Dice Similarity Coefficients of 81.05% for breast cancer, 76.41% for brachial plexus nerves, and 87.75% for infantile hemangioma segmentation on three public datasets.
Accurately segmenting lesions in ultrasound images is challenging due to the difficulty in distinguishing boundaries between lesions and surrounding tissues. While deep learning has improved segmentation accuracy, there is limited focus on boundary quality and its relationship with body structures. To address this, we introduce UBBS-Net, a dual-branch deep neural network that learns the relationship between body and boundary for improved segmentation. We also propose a feature fusion module to integrate body and boundary information. Evaluated on three public datasets, UBBS-Net outperforms existing methods, achieving Dice Similarity Coefficients of 81.05% for breast cancer, 76.41% for brachial plexus nerves, and 87.75% for infantile hemangioma segmentation. Our results demonstrate the effectiveness of UBBS-Net for ultrasound image segmentation. The code is available at https://github.com/apple1986/DBF-Net.
