摘要:

超声是一种在健康筛查中至关重要的诊断技术,具有非侵入性、成本效益和无辐射的优势,因此被广泛应用于结节的诊断。然而,它严重依赖于超声技师的专业知识和临床经验。在超声图像中,一个单一的病灶可能在不同横截面视图中呈现异质性外观,这使得进行单病灶检查变得困难。超声技师通常通过检查病灶特征和周围结构如腺体和导管来区分不同的病灶,这过程繁琐且耗时。为了解决这个问题,我们收集了数百个乳腺超声视频,并构建了一个病灶重识别系统,该系统由两部分组成:基于深度学习模型的提取器,可以从中提取输入视频片段的特征向量,以及一个实时聚类算法,能够自动将特征向量按病灶分组。该系统取得了令人满意的结果,并展示了区分超声视频的能力。据我们所知,这是首次将重识别技术应用于超声领域。

英文摘要:

Ultrasound is a vital diagnostic technique in health screening, with the advantages of non-invasive, cost-effective, and radiation free, and therefore is widely applied in the diagnosis of nodules. However, it relies heavily on the expertise and clinical experience of the sonographer. In ultrasound images, a single nodule might present heterogeneous appearances in different cross-sectional views which makes it hard to perform per-nodule examination. Sonographers usually discriminate different nodules by examining the nodule features and the surrounding structures like gland and duct, which is cumbersome and time-consuming. To address this problem, we collected hundreds of breast ultrasound videos and built a nodule reidentification system that consists of two parts: an extractor based on the deep learning model that can extract feature vectors from the input video clips and a real-time clustering algorithm that automatically groups feature vectors by nodules. The system obtains satisfactory results and exhibits the capability to differentiate ultrasound videos. As far as we know, it's the first attempt to apply re-identification technique in the ultrasonic field.
