In the past decade, there has been a resurgence in the field of unobtrusive cardiomechanical assessment, through advancing methods for measuring and interpreting ballistocardiogram (BCG) and seismocardiogram (SCG) signals. Novel instrumentation solutions have enabled BCG and SCG measurement outside of clinical settings, in the home, in the field, and even in microgravity. Customized signal processing algorithms have led to reduced measurement noise, clinically relevant feature extraction, and signal modeling. Finally, human subjects physiology studies have been conducted using these novel instruments and signal processing tools with promising results. This paper reviews the recent advances in these areas of modern BCG and SCG research.
在过去的十年中，通过推进测量和解释心冲击图（BCG）和地震心动图（SCG）信号的方法，非侵入性心脏力学评估领域出现了复苏。新型仪器解决方案使 BCG 和 SCG 测量能够在临床环境之外进行，无论是在家里、在野外，甚至是在微重力环境中。定制的信号处理算法减少了测量噪声，提取了与临床相关的特征，并对信号进行了建模。最后，使用这些新型仪器和信号处理工具进行了人体生理学研究，取得了有希望的结果。本文回顾了现代 BCG 和 SCG 研究中这些领域的最新进展。
