متن کاملNoninvasive Method for Measuring Local Pulse Wave Velocity by Dual Pulse Wave Doppler: In Vitro and In Vivo Studies
OBJECTIVES To evaluate the validity and reproducibility of a noninvasive dual pulse wave Doppler (DPWD) method, which involves simultaneous recording of flow velocity of two independent sample volumes with a measurable distance, for measuring the local arterial pulse wave velocity (PWV) through in vitro and in vivo studies. METHODS The DPWD mode of Hitachi HI Vision Preirus ultrasound system ...
متن کاملNew Method for Measure Regional Pulse Wave Velocity by Means of Rf Ultrasonic Signals
The aim of this paper is to describe a non-invasive method of examination of the local pulse wave velocity. The measurements were carried out in the elastic silicon model of the artery immersed in water tank. Two synchronized ultrasonic apparatus VED with the ultrasonic radio frequency echoes acquisition for evaluation of the arterial elasticity, developed by the author, were used. The zerocros...
متن کاملDetection of Concrete Damage Using Ultrasonic Pulse Velocity Method
This paper investigates the efficiency of Ultrasonic Pulse Velocity (UPV) method in detecting cracks and flaws inside the concrete. A series of concrete beams and slab specimens were cast and damaged to simulate the different mechanisms possible in a reinforced concrete deck due to mechanical loading. Two types of simulated cracks, namely, cracks perpendicular and cracks parallel to axis of bea...
متن کاملEstimation of arterial pulse wave velocity with a new improved Tissue Doppler method
The mechanical properties of the large arteries are important determinants in the circulation physiology. Quantities associated with vessel wall elasticity are of particular interest since they offer a possibility to separate diseased arteries from healthy. Pulse wave velocity (PWV) is a local measure of the arterial wall elasticity. This paper describes a new improved method for non-invasive l...
