Title: | Ballistocardiography monitoring system based on optical fiber interferometer aided with heartbeat segmentation algorithm | Authors: | Chen, SY Tan, FZ Lyu, WM Yu, CY |
Issue Date: | Oct-2020 | Source: | Biomedical optics express, Oct. 2020, v. 11, no. 10, p. 5458-5469 | Abstract: | An optical fiber interferometer-based ballistocardiography (BCG) monitoring system aided with the UK complex detection algorithm is proposed in this paper. A new phase modulation method based on a moving-coil transducer is developed to address the problem of signal fading in the optical fiber interferometer and keep the system in quadrature by the closed loop controller. As a result, a stable BCG signal without baseline drift can be obtained. This BCG monitor based on optical fiber interferometer using phase modulation method owns the advantages of compact, low-cost, portable, and user-friendly. In addition, an end-to-end modified U-net is developed to conduct pixel-wise classification in the BCG signal. This network can achieve high accuracy and shows its capability to segment UK complex and body movement in the BCG signal. In conclusion, the proposed BCG monitoring system with UK complex segmentation algorithm is potential and promising in healthcare applications.
