摘要:

乳腺癌是全球主要致死原因之一,因此迫切需要早期且准确的诊断技术。尽管超声成像是一种广泛用于乳腺癌筛查的技术,但它面临诸如因肿瘤形态变化导致的边界勾画不佳,以及因图像质量不一致而降低诊断准确性等挑战。为应对这些挑战,我们提出了用于乳腺病变分割与分类的新型深度学习(DL)框架。我们为精确映射与注意力驱动的 LinkNet(PMAD-LinkNet)分割框架引入了一种精确映射机制(PMM),该机制通过形态变化分析动态调整空间映射,从而实现肿瘤边界的精确像素级细化。随后,我们为组件特定特征增强分类器(CSFEC-Net)引入了一个组件特定特征增强模块(CSFEM)。通过多层次注意力方法,CSFEM 放大了良性、恶性和正常组织的区分性特征。我们将所提出的框架与现有文献以及多种最先进的卷积神经网络(CNN)架构进行了评估对比。所得结果表明,我们的分割模型达到了 98.1% 的准确率、96.9% 的 IoU 和 97.2% 的 Dice 系数。对于分类模型,达到了 99.2% 的准确率,F1 分数、精确率和召回率分别为 99.1%、99.3% 和 99.1%。

英文摘要:

Breast cancer is one of the leading causes of death globally, and thus there is an urgent need for early and accurate diagnostic techniques. Although ultrasound imaging is a widely used technique for breast cancer screening, it faces challenges such as poor boundary delineation caused by variations in tumor morphology and reduced diagnostic accuracy due to inconsistent image quality. To address these challenges, we propose novel Deep Learning (DL) frameworks for breast lesion segmentation and classification. We introduce a precision mapping mechanism (PMM) for a precision mapping and attention-driven LinkNet (PMAD-LinkNet) segmentation framework that dynamically adapts spatial mappings through morphological variation analysis, enabling precise pixel-level refinement of tumor boundaries. Subsequently, we introduce a component-specific feature enhancement module (CSFEM) for a component-specific feature-enhanced classifier (CSFEC-Net). Through a multi-level attention approach, the CSFEM magnifies distinguishing features of benign, malignant, and normal tissues. The proposed frameworks are evaluated against existing literature and a diverse set of state-of-the-art Convolutional Neural Network (CNN) architectures. The obtained results show that our segmentation model achieves an accuracy of 98.1%, an IoU of 96.9%, and a Dice Coefficient of 97.2%. For the classification model, an accuracy of 99.2% is achieved with F1-score, precision, and recall values of 99.1%, 99.3%, and 99.1%, respectively.
