Velocity Selective Radiofrequency Pulse Trains

Journal of Magnetic Resonance, 1999
The incorporation of velocity-encoding gradient pulses in RF-pulse trains is proposed and examined. Velocity selective perturbation is shown to be analogous in many respects to the well established use of trains of short RF-pulses for chemical shift selective perturbation.

CAROTID‐FEMORAL PULSE WAVE VELOCITY*

Journal of the American Geriatrics Society, 1968
A bstract Simultaneous records of the pulse waves were obtained from the right common carotid artery and the right femoral artery by means of piezo‐electric microphones in 26 persons whose ages ranged from 15 to 92 years.

Pulse Dispersion and Pulse Velocity

1996
Any physically consistent setting up of a pulse problem should incorporate three basic components: a source of the perturbation, a medium of propagation and a receiver spatially separated from the source. To obtain a reproducible experiment one should eliminate all other sources of perturbations, and initiate the signal in the medium at rest at a ...

Velocity of Electron Pulses

Nature, 1954
ONE of us1 has noted that the velocity of electrons has never been measured under conditions which allow no alternative interpretation. A linear velocity of displacement is a necessary inference only where two successive events, departure and arrival, have been observed which are localized and distinct, both in space and in time.

Pulse Wave Velocity in Kawasaki Disease

Angiology, 2016
Kawasaki disease (KD) is an acute childhood febrile disease of unknown etiology. It exhibits not only coronary artery aneurysms in some cases but also systemic vasculitis. Whether KD is associated with accelerated atherosclerosis remains debatable. The measurement of pulse wave velocity (PWV) is useful as a simple, noninvasive measurement of arterial ...

Pulse wave velocities in the aorta

Bulletin of Mathematical Biology, 1984
This paper is an analytical study on the pulse wave velocities in the aorta. In conformity to a physiologic state of loading, the distensibility of the vessel wall has been accounted for. The wall material is treated by using the theory of large elastic deformations. The orthotropicity of wall tissues and the effect of the surrounding tissues have been
