Electromagnetic induction imaging (EII) is an attractive imaging modality due to its contactless operation, low cost, and good penetration depth. To implement real-time imaging, in applications such as object tracking or functional biomedical imaging, fast data acquisition is required. To proceed toward this goal, in this article, we propose the use of a single coil for 3-D EII along with a fast inversion approach. To collect sufficient data that allow 3-D imaging, we propose two approaches: collecting data at multiple coil’s drive current levels and collecting data with multiple tank circuit’s capacitor values. We show that the use of such data when using a single coil allows for 3-D EII. For proof-of-concept experiments, we use a commercial data acquisition board, that is, LDC1614EVM module, and multilayer planar coils made by Texas Instruments.

单线圈多深度电磁感应成像

由于其非接触式操作、低成本和良好的穿透深度，电磁感应成像 (EII) 是一种有吸引力的成像方式。为了实现实时成像，在对象跟踪或功能生物医学成像等应用中，需要快速的数据采集。为了实现这一目标，在本文中，我们建议将单个线圈用于 3-D EII 以及快速反演方法。为了收集足够的数据以进行 3-D 成像，我们提出了两种方法：在多个线圈的驱动电流水平收集数据和使用多个储能电路的电容器值收集数据。我们表明，在使用单个线圈时使用此类数据允许 3-D EII。对于概念验证实验，我们使用商用数据采集板，即 LDC1614EVM 模块和德州仪器制造的多层平面线圈。
