Intra-corporal localization and communications using UWB

在我们目前为期四年的联合项目UWB在医学中，我们能够证明适用于医疗传感应用和无线传感器节点通信的生物医学环境中的无载波脉冲UWB无线电。我们开发了模拟信号处理算法，最先进的UWB天线和一个高度灵活的脉冲UWB芯片组的接收和发送应用。在UKoLos的最后两年，我们仍然希望解决一些重要的开放点。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。具体而言，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·介入设备（如导管）的定位出现了重大挑战，这些挑战超出了迄今为止所做的研究。在电路设计领域，我们将展示一个新的单基地UWB雷达在单芯片上的电路集成的进一步增加。此外，发散UWB标准化将使用低功耗脉冲发生器，这是必不可少的医疗UWB的全球接受的新的可调谐性概念，并为患者的流动性。方法、电路和天线的集合将在测试床中进行验证，该测试床解决了在存在有限带宽、低SNR、多径传播和干扰的情况下，以毫米波精度对人体内的介入器械进行体表成像、定位和运动跟踪的主题。

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.
