Microwave breast imaging has seen significant academic and commercial development in recent years, with four new operational microwave imaging systems used with patients since 2016. In this paper, a comprehensive review of these recent clinical advances is presented, comparing patient populations and study outcomes. For the first time, the designs of operational microwave imaging systems are compared in detail.
First, the current understanding of dielectric properties of human breast tissues is reviewed, considering evidence from operational microwave imaging systems and from dielectric properties measurement studies. Second, design features of operational microwave imaging systems are discussed in terms of advantages and disadvantages during clinical operation.
Reported results from patient imaging trials are compared, contrasting the principal results from each trial. Additionally, clinical experience from each trial is highlighted, identifying desirable system design features for clinical use.
Increasingly, evidence from patient imaging studies indicate that a contrast in dielectric properties between healthy and cancerous breast tissues exists. However, despite the significant and encouraging results from patient trials, variation still exists in the microwave imaging system design.
This study seeks to define the current state of the art in microwave breast imaging, and identify suitable design characteristics for ease of clinical use.
近年来，微波乳房成像技术在学术和商业上都取得了显著的发展，自 2016 年以来，已有四种新的可操作微波成像系统用于患者。本文对这些最近的临床进展进行了全面回顾，比较了患者人群和研究结果。首次详细比较了可操作微波成像系统的设计。
首先，回顾了人体乳房组织介电特性的现有认识，同时考虑了来自可操作微波成像系统和介电特性测量研究的证据。其次，根据临床操作中的优缺点，讨论了可操作微波成像系统的设计特点。
比较了患者成像试验的报告结果，对比了每个试验的主要结果。此外，突出了每个试验的临床经验，确定了临床应用中理想的系统设计特点。
越来越多的来自患者成像研究的证据表明，健康和癌变的乳房组织之间存在介电特性的差异。然而，尽管患者试验取得了重大而令人鼓舞的结果，但微波成像系统的设计仍存在差异。
本研究旨在定义微波乳房成像的当前技术水平，并确定适合临床应用的设计特点。
