Intra-corporal localization and communications using UWB

在我们目前为期四年的医学超宽带联合项目中，我们能够证明无载波脉冲超宽带无线电用于医学传感应用和生物医学环境中的无线传感器节点通信的适用性。我们开发了模拟信号处理算法，最先进的超宽带天线和高度灵活的脉冲超宽带芯片组，用于接收和传输应用。在UKoLos的最后2年期间，我们仍然希望解决一些重要的开放问题。医学2的这个新项目提案现在将把注意力转向最终可以放置在人体内的超宽带系统。具体来说，两个潜在的应用将指导拟议项目中进行的研究：•与植入物的通信•导管等介入设备的定位出现了重大挑战，超出了目前所做的调查。在电路设计领域，我们将展示一种新型单稳态超宽带雷达在单芯片上进一步提高电路集成度。此外，将使用低功耗脉冲发生器的新可调性概念来解决UWB标准化的分歧，这对于全球接受医疗UWB和患者移动性至关重要。方法、电路和天线的集成将在一个试验台进行验证，该试验台解决了人体表面成像、人体内部介入设备的定位和运动跟踪等主题，具有毫米波精度，存在受限带宽、低信噪比、多径传播和干扰。

In our current four years joint project UWB in Medicine we were able to demonstrate the suitability of a carrierless impulse UWB radio for medical sensing applications and wireless sensor node communications in biomedical settings. We developed analog signal processing algorithms, state of the art UWB antennas and a highly flexible impulse UWB chipset for receive and transmit applications. There are still important open points which we want to address in this final 2-years period of UKoLos. This new project proposal UWB in Medicine 2 will now turn its attention to UWB systems which can eventually be placed inside of the human body. Two potential applications, specifically, will guide the research undertaken in the proposed project:• Communication with implants• Localization of interventional devices, such as cathetersSignificant challenges arise, which move beyond the investigations done so far. In the field of circuit design we will demonstrate a further increase in circuit integration with a novel monostatic UWB radar on a single chip. Further, diverging UWB standardization will be addressed using new tunability concepts for low power consumption pulse generators, which are essential for global acceptance of medical UWB, and for patient mobility. The ensemble of methods, circuits, and antennas will be validated in a test bed which addresses the topics of imaging of the body surface, localization and movement-tracking of interventional devices inside the human body, with millimeter-wave accuracy, in the presence of restricted bandwidth, low SNR, multipath propagation and interference.
