estimation of carotid artery pulse wave velocity by doppler ultrasonography
background: pulse wave velocity (pwv) is widely used for estimating the stiffness of an artery. v arious invasive and non-invasive methods have been developed to determine pwv over the years. in the present research , the non-invasive estimation of the pwv of large arteries was used as an index for arterial stiffness. methods: a dynamic model based on the navier-stokes equations coupled to elas...
متن کاملMicro-pulse upconversion Doppler lidar for wind and visibility detection in the atmospheric boundary layer.
For the first time, to the best of our knowledge, a compact, eye-safe, and versatile direct detection Doppler lidar is developed using an upconversion single-photon detection method at 1.5 μm. An all-fiber and polarization maintaining architecture is realized to guarantee the high optical coupling efficiency and the robust stability. Using integrated-optic components, the conservation of etendu...
متن کاملPulse subtraction Doppler
Recent advances have demonstrated the feasibility of molecular imaging using targeted microbubbles and ultrasound. One technical challenge is to selectively detect attached bubbles from those freely flowing bubbles and surrounding tissue. Pulse Inversion Doppler is an imaging technique enabling the selective detection of both static and moving ultrasound contrast agents: linear scatterers gener...
متن کاملThe Novel Nonlinear Adaptive Doppler Shift Estimation Technique and the Coherent Doppler Lidar System Validation Lidar
The signal processing aspect of a 2-μm wavelength coherent Doppler lidar system under development at NASA Langley Research Center in Virginia is investigated in this paper. The lidar system is named VALIDAR (validation lidar) and its signal processing program estimates and displays various wind parameters in real-time as data acquisition occurs. The goal is to improve the quality of the current...
متن کاملReprint 898 Forecasting Headwind Profiles and Low Level Windshear Using LIDAR Velocity Data and a Chaotic Oscillatory-based Neural Network
Two Doppler LIght Detection And Ranging (LIDAR) systems have been operated by the Hong Kong Observaotry (HKO) at the Hong Kong International Ai rport (H KIA) for the det ection and alerting of low-level windshear to be encountered by the aircraft. The windshear al erting algorithm is based on the automatic identification of abrupt changes of headwinds along the glide paths of HKIA, which are me...
