RISRelations of Radial Vibration of the Arterial Wall to Pulsatile Parameters in Blood Flow for Extraction of Arterial Indices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Given the wide utility of radial vibration of the arterial wall for clinical values, this paper presents a theoretical study on the relations of radial vibration of the arterial wall to pulsatile parameters in blood flow. ...
Radial and Axial Displacement of the Initially-Tensioned Orthotropic Arterial Wall Under the Influence of Harmonics and Wave Reflection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study examines radial and axial displacement of the arterial wall under the influence of harmonics and wave reflection for the role of axial wall displacement in pulsatile wave propagation. The arterial wall is modeled ...

A Vibrating-String Model for Closed-Loop Wave Transmission and Reflection Between the Aorta and Periphery
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A tube-load model is used to reconstruct aortic pressure waveform from peripheral pressure waveform. Yet, the reconstructed aortic pressure waveform is greatly affected by load impedance used. In this work, a vibrating-string ...
Is It Feasible to Reconstruct Aortic Pressure Waveform Based on a One-Dimensional Uniform Model of the Arterial Tree?
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on a one-dimensional (1D) uniform model of the arterial tree, various machine-learning techniques have been explored to reconstruct aortic pressure waveform (APW) from peripheral pressure waveform (PPW). This study ...
A Hypothesized Mechanistic Model of Longitudinal Wall Motion at the Common Carotid Artery
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: By adopting a physics-physiology integrative approach, this work hypothesizes a mechanistic model of longitudinal wall motion ux(t) at the common carotid artery (CCA) and explores its antegrade amplitude ux0-ante and ...
Radial and Axial Motion of the Initially Tensioned Orthotropic Arterial Wall in Arterial Pulse Wave Propagation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the arterial wall modeled as an initially tensioned thin-walled orthotropic tube, this study aims to analyze radial and axial motion of the arterial wall and thereby reveal the role of axial motion and two initial ...
Axial Wall Displacement at the Common Carotid Artery is Associated With the Lamb Waves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As compared with its radial wall displacement, axial wall displacement at the common carotid artery (CCA) carries independent clinical values, but its physical mechanisms are unclear. This study aims to investigate whether ...
