I am thrilled to announce that our paper entitled “In Vivo Characterization of Central Arterial Properties using a Miniaturized pMUT Array compared to a Clinical Transducer: A Feasibility Study Towards Wearable Pulse Wave Imaging” was published in IEEE Transactions on Biomedical Engineering! The preprint of the paper is available online: https://lnkd.in/d9FiUFvk https://lnkd.in/dMfuGHpM Cardiovascular diseases and risk-factors are becoming more prevalent globally, yet current methods for assessing arterial health are often limited to clinical settings. Wearable ultrasound technology offers the potential for at-home and continuous monitoring of arterial parameters, which may be useful for early disease detection and optimizing treatment strategies. However, the use of ultrafast motion estimation techniques, like Pulse Wave Imaging (PWI), have been largely unexplored for transducers designed for wearable use, as these devices may face a tradeoff between form-factor and imaging performance. In this study, we explored the integration of wearable ultrasound technology with PWI, a noninvasive, ultrasound-elasticity technique that can estimate arterial mechanics including stiffness, compliance, and blood pressure. This in-vivo feasibility study showcases the potential of performing PWI with hardware suitable for future wearable applications, highlighting new opportunities for cardiovascular health monitoring with further development. Special thanks to our collaborators at TDK-- Marco Travagliati, Leonardo Baldasarre, and Stephen Bart--who designed the miniaturized pMUT array used in this work and worked closely with us throughout the entire study . Thanks to Tuhin Roy, Paul Kemper, Pengcheng Liang, and Elisa Konofagou from our lab (Ultrasound Elasticity Imaging Laboratory at Columbia University) for their collaboration and support.
