Global Oscillations at Low Frequency from the SOHO mission (GOLF)
The GOLF experiment on the SOHO mission aims to study the internal structure of the sun by measuring the spectrum of global oscillations in the frequency range 10−7 to 10−2 Hz. Bothp andg modeExpand

Influence of catheter position on estimated strain in intravascular elastography
In elastography, an erroneous strain estimate is obtained when the radial strain and the probing ultrasound beam are not properly aligned: the "strain projection artifact". In practice, an angleExpand

Decorrelation characteristics of transverse blood flow along an intravascular array catheter
In recent years, a new method to measure transverse blood flow based on the decorrelation of radio frequency (RF) signals has been introduced. In this paper, we investigated the decorrelationExpand
