Abstract：
Impedance measuring acquisition systems focused on breast tumor detection, as well as image processing techniques for 3D imaging, are reviewed in this paper in order to define potential opportunity areas for future research. The description of reported works using electrical impedance tomography (EIT)-based techniques and methodologies for 3D bioimpedance imaging of breast tissues with tumors is presented. The review is based on searching and analyzing related works reported in the most important research databases and is structured according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) parameters and statements. Nineteen papers reporting breast tumor detection and location using EIT were systematically selected and analyzed in this review. Clinical trials in the experimental stage did not produce results in most of analyzed proposals (about 80%), wherein statistical criteria comparison was not possible, such as specificity, sensitivity and predictive values. A 3D representation of bioimpedance is a potential tool for medical applications in malignant breast tumors detection being capable to estimate an ap-proximate the tumor volume and geometric location, in contrast with a tumor area computing capacity, but not the tumor extension depth, in a 2D representation.
摘要：
阻抗测量采集系统专注于乳腺肿瘤检测，以及用于3D成像的图像处理技术，本文对其进行了综述，以确定未来研究的潜在机会领域。介绍了使用基于电阻抗断层扫描（EIT）的技术和方法对具有肿瘤的乳腺组织进行3D生物阻抗成像的报告工作的描述。审查基于搜索和分析最重要的研究数据库中报告的相关工作，并根据系统审查和荟萃分析（PRISMA）参数和陈述的首选报告项目进行结构。本文系统地选择并分析了19篇报告使用EIT进行乳腺肿瘤检测和定位的论文。实验阶段的临床试验在大多数分析的建议中没有产生结果（约80％），其中统计标准比较是不可能的，如特异性，敏感性和预测值。生物阻抗的3D表示是用于恶性乳腺肿瘤检测中的医学应用的潜在工具，能够估计接近的肿瘤体积和几何位置。与肿瘤区域计算能力相反，但不是肿瘤的延伸深度，在2D表示中。
