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，我们能够展示无载波脉冲超宽带无线电在生物医学环境中用于医疗传感应用和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UWB天线和高度灵活的冲激UWB芯片组，用于接收和发送应用。在UKoLOS的最后两年期间，我们仍然有一些重要的开放点需要解决。这个新的项目提案UWB in Medicine 2现在将把注意力转向最终可以放置在人体内的UWB系统。具体地说，两个潜在的应用将指导拟议项目中进行的研究：·与植入物的沟通·介入设备的本地化，如导管的本地化出现了重大挑战，这些挑战超出了迄今所做的研究。在电路设计领域，我们将展示一种新型的单基地超宽带雷达在单芯片上的电路集成度的进一步提高。此外，将使用低功耗脉冲发生器的新可调谐概念来解决不同的UWB标准化问题，这对全球接受医用UWB和患者移动性至关重要。这些方法、电路和天线的组合将在试验台上进行验证，该试验台解决的主题是人体表面的成像、人体内介入设备的定位和运动跟踪，在带宽受限、低信噪比、多径传播和干扰的情况下，具有毫米波精度。

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.
