Dual-beam vector Doppler has the potential to improve peak systolic blood velocity measurement accuracy by automatically correcting for the beam-flow Doppler angle. Using a modified linear-array system with a split receive aperture, we have assessed

Development of an advanced digital image processor for real-time speckle suppression in routine ultrasonic scanning
Autor: T. Loupas, P.L. Allan, W.N. McDicken, T. O. M. Anderson
Publikováno v: Ultrasound in medicinebiology. 20(3)
This paper describes a digital image processor for ultrasonic speckle suppression that was explicitly designed to satisfy the requirements of detail preservation, adequate smoothing and real-time operation. The first two of these requirements were ad

Ultrasound assessment of the position of the tongue during induction of anaesthesia
Autor: L.J. Abernethy, G.B. Drummond, P.L. Allan
Publikováno v: British journal of anaesthesia. 65(6)
Tongue position was assessed in 15 female patients at induction of anaesthesia with either thiopentone or propofol. A video recording of a midline sagittal section of the tongue was made using an ultrasound transducer placed below the chin, and repre
