Pulse Arrival Time Segmentation into Cardiac and Vascular Intervals – Implications for Pulse Wave Velocity and Blood Pressure Estimation
Pulse wave velocity (PWV) is a pressure-dependent marker of arterial stiffness, wherefore pulse arrival time (PAT) has been widely investigated for cuff-less blood pressure (BP) estimation. However, PAT is typically biased by a cardiac delay and peripheral vasculature. Therefore, we demonstrate an ultrasound-based method for central PAT segmentation into cardiac isovolumic contraction (IVC) and vascular pulse transit time (PTT). Contrasting peripheral PAT, central PTT-based PWV explained more than twice as much variability in the reference PWV and yielded significantly lower BP estimation errors. Thereby this unilateral arterial stiffness assessment bears the potential to improve cardiovascular risk assessment in clinical routines... Read more

Ultrasound-Based Attenuation Imaging for the Non-Invasive Quantification of Liver Fat – A Pilot Study on Feasibility and Inter-Observer Variability
Attenuation imaging is a novel, ultrasound-based technique to objectively detect and quantify liver steatosis. In this study, we evaluated the performance and inter-observer variability of attenuation imaging and compared it to a known quantification method of liver fat, the hepatorenal... Read more

Real-Time Blood Pressure Estimation From Force-Measured Ultrasound
Common techniques to measure blood pressure include an arterial catheter, an oscillometric pressure cuff, or an auscultatory pressure cuff. Oscillometric and auscultatory cuffs have an associated error, cannot be used continuously, and fully collapse the brachial artery. An auscultatory cuff... Read more
