In this paper we present the T-SCAN technology and its use as a diagnostic tool for breast cancer detection. We show, using theoretical models with simplified geometries, that displaying planar two-dimensional maps of the currents detected at the breast's surface relate to the electric field distribution within the breast. This distribution is a manifestation of the bulk spatial inhomogeneities in the complex dielectric constant that represent the various tissue types. These differences may be used to discriminate between various pathological states. We furthermore illustrate a useful classifier, based on admittance data measured up to 2 kHz, and we argue that low frequency impedance measurements can be used successfully in breast cancer diagnosis.
在本文中，我们介绍了T-SCAN技术及其作为乳腺癌检测诊断工具的应用。我们使用具有简化几何形状的理论模型表明，显示在乳房表面检测到的电流的平面二维图与乳房内的电场分布有关。这种分布是代表各种组织类型的复介电常数中大量空间不均匀性的一种表现。这些差异可用于区分各种病理状态。我们还展示了一种基于高达2 kHz测量的导纳数据的有用分类器，并认为低频阻抗测量可成功用于乳腺癌诊断。
