“…They estimated the transient change in viscoelasticity during a flowmediated dilation. Recently, Saito et al [30] used the same technique to measure changes in the viscoelastic parameters of a radial artery to evaluate the endothelial function. The estimated viscoelastic parameters and experimental methods for measuring the arterial pressure and diameter are summarized in Table 1.…”

“…Although a highresolution (spatial accuracy of less than 1 μm) US measurement technique using the phased tracking method has been developed [28], its clinical application has not yet been fully established. Tonometry has been frequently used in previous in vivo experiments [26][27][28][29][30] for local pressure measurement, but arterial wall compression can affect the intramural pressure, wall motion, and smooth muscle activity [26]. Another limitation is related to the theory of using a thin-walled tube to compute the wall elasticity.…”

Hasegawa and Kanai [28] and Saito et al [30] used the Voigt model to estimate the viscoelastic parameters of human radial arteries by simultaneously measuring pressures and diameters in vivo. Ghigo et al [25] included a nonlinear term ( ̇2 ) in the Voigt model to improve the P-D relationship of a sheep's artery.…”

Arteries, which carry blood from the heart to the peripheral tissues, are continuously stressed by pressure pulsation. Pathological changes in arterial walls could cause high-risk cardiovascular diseases, such as heart attack and stroke. Once established, vascular diseases progress by the continual remodeling of the arterial wall, which includes changes in the composition and function of the wall tissues. An arterial wall has both elastic and viscous characteristics, and pathological and degenerative changes in the wall tissue affect the viscoelastic behavior of the artery wall. The arterial viscoelasticity may provide useful information regarding the development and progression of arterial diseases. However, only the wall stiffness has been considered as a clinical diagnostic index for atherosclerosis. Only a few studies have assessed the viscoelasticity of an intact artery, and further studies are necessary to employ the wall viscoelasticity as a physical marker for diagnosing vascular diseases. Accordingly, this study focuses on arterial wall viscosity assessment and its possible clinical applications. In vitro and in vivo tissue viscoelasticity measurement techniques are reviewed, and constitutive models used to assess viscoelastic artery wall behaviors are summarized. Because wall viscoelasticity depends on the tissue composition and function, pathological changes in the arterial wall during atherosclerosis and the contribution of vascular cells to viscoelasticity are discussed. Finally, the recent progress in clinical tools for measuring arterial viscoelasticity is reviewed.

“…Ultrasonic method ensures real-time elastography, but is suffered from relatively low resolution because of the inherent diffraction. As for measurement techniques for dimension or strain of human organs, efforts have been continuously made, and the achievements are reported also in recent papers [17,18,19,20]. Magnetic resonance elastography (MRE) and optical coherence elastography (OCE) can provide higher resolution and achieve stronger contrast between the blood and vessels [21,22,23,24].…”

To pursue higher precision and wider range of noninvasive vascular deformation measurement for medical diagnosis, this paper presents a photoacoustic measurement method based on the acoustic resonance perspective other than usual imaging-based method. In-vitro experiments were conducted for red-ink-filled soft tubes having diameter of less than 1 mm embedded in a tissue-mimicking phantom. A 3-W laser diode and a 2-MHz ultrasound transducer together with an external compressing device were used. Percentage error of 4% was marked in estimating the inner diameter of tube samples. The results demonstrated that the proposed method was feasible to detect a sub-millimeter deformation for thin tubes with ultrasound transducer of relatively low center frequency and electronic circuit of limited temporal resolution.

Vascular tone plays a vital role in regulating blood pressure and coronary circulation, and it determines the peripheral vascular resistance. Vascular tone is dually regulated by the perivascular nerves and the cells in the inside lining of blood vessels (endothelial cells). Only a few methods for measuring vascular tone are available. Because of this, determining vascular tone in different arteries of the human body and monitoring tone changes is a vital challenge. This work presents an approach for determining vascular tone in human extremities based on multi-channel bioimpedance measurements. Detailed steps for processing the bioimpedance signals and extracting the main parameters from them have been presented. A graphical interface has been designed and implemented to display the vascular tone type in all channels with the phase of breathing during each cardiac cycle. This study is a key step towards understanding the way vascular tone changes in the extremities and how the nervous system regulates these changes. Future studies based on records of healthy and diseased people will contribute to increasing the possibility of early diagnosis of cardiovascular diseases.
