Biomedical Engineering Research Seminar

Seismocardiography (SCG) is a non-invasive method to monitor the mechanical activity of the cardiovascular system based on vibrations of the chest surface. This method has shown promise in providing clinically relevant information for cardiovascular diseases such as heart failure and atrial fibrillation. In this presentation, I will present our research progress in developing novel contactless methods to acquire and analyze SCG signals. In the first part of the presentation, I will describe our efforts in developing a vision-based technique to extract chest vibrations associated with SCG from chest videos recorded by a smartphone. SCG signals are conventionally measured using accelerometers attached to the chest. Vision-based techniques can improve the accessibility of this novel cardiovascular monitoring method and make it available to the public given the wide access to smartphones. In the second part of the talk, I will discuss why it is important to carefully select the SCG measurement location on the chest for estimating cardiac time intervals from the SCG signals. Overall, our research goal in this project is to improve patient outcomes and quality of life by developing accurate and robust cardiovascular monitoring methods based on SCG.


Dr. Amirtahà Taebi is an Assistant Professor of Biomedical Engineering at Mississippi State University. He is an Associate Editor in BMC Research Notes, an Editorial Board Member of Scientific Reports, and a Guest Editor in several journals including Bioengineering. Before joining MSU, he was a postdoctoral fellow of Biomedical Engineering at the University of California, Davis from 2018 to 2021. In the industrial setting, he led the Advanced Signal Processing team at Infrasonix, Inc, a biomedical engineering start-up based in GA, from 2020 to 2021. Amirtahà received his PhD in Mechanical Engineering from the University of Central Florida, Orlando, in 2018 after completing his MSc in Biomedical Engineering at Politecnico di Milano, Italy, in 2013. Before joining Polimi, he earned his BSc in Mechanical Engineering from the Sharif University of Technology, Iran, in 2010. His current work focuses on developing noninvasive and remote methods and devices for cardiovascular monitoring.
