摘要

膝关节振动关节成像(VAG)信号的来源定位对于开发一种无创的人类膝关节病理诊断工具具有重要意义。本文讨论了相关技术在VAG信号源定位中的可能应用。对4例膝关节异常患者进行多通道VAG信号采集。初步实验结果表明，相关分析可能为定位VAG信号源提供一种实用的方法。

Time delay estimation for source localization of vibroarthrographic signals from human knee joints

Source localization of knee vibroarthrographic (VAG) signals is of significance for the development of a noninvasive tool for diagnosis of pathology in human knee joints. This paper discusses the possible application of correlation techniques to VAG signal source localization. Multi-channel VAG signals were obtained from four subjects with knee joint abnormalities. Preliminary experimental results indicate that correlation analysis could potentially provide a practical method for localizing sources of VAG signals.
