摘要

用于微波成像(MI)系统的体上天线可以将能量引导到身体周围而不是通过身体,从而降低系统的整体信噪比(SNR)。这项工作通过模拟和实验,介绍并量化了现代金属背衬射频吸收泡沫与体内天线的结合使用,以抑制身体周围的能量流动。本文演示了头部成像系统,但该原理可应用于身体的任何部位,包括躯干或四肢。使用Ansys HFSS对计算模型进行了数值模拟。建立了一个带有嵌入式天线的头盔形式的物理原型,以将模拟与测量数据进行比较。模拟和测量表明,使用这种金属背衬的RF吸收泡沫可以将来自发射(Tx)和接收(Rx)天线的绕体耦合显著减少约10dB。因此,使用这种低成本和可负担的方法,MI系统的总体SNR可以显著提高。

Reducing Non-Through Body Energy Transfer in Microwave Imaging Systems
On-body antennas for use in microwave imaging (MI) systems can direct energy around the body instead of through the body, thus degrading the overall signal-to-noise ratio (SNR) of the system. This work introduces and quantifies the usage of modern metal-backed RF absorbing foam in conjunction with on-body antennas to dampen energy flowing around the body, using both simulations and experiments. A head imaging system is demonstrated herein but the principle can be applied to any part of the body including the torso or extremities. A computational model was simulated numerically using Ansys HFSS. A physical prototype in the form of a helmet with embedded antennas was built to compare simulations with measured data. Simulations and measurements demonstrate that usage of such metal-backed RF-absorbing foams can significantly reduce around-body coupling from Transmit (Tx) and Receive (Rx) antennas by approximately 10 dB. Thus, the overall SNR of the MI system can be substantially improved using this low-cost and affordable method.
