Speckle tracking for multi-dimensional flow estimation

Ultrasonics, 2000
Speckle tracking methods overcome the major limitations of current Doppler methods for flow imaging and quantification: angle dependence and aliasing. In this paper, we review the development of speckle tracking, with particular attention to the advantages and limitations of two-dimensional algorithms that use a single transducer aperture.

Speckle Tracking : ACTO Tracking durch optische Maussensoren

2016
Der Einsatz von Tangible User Interfaces (TUIs) erscheint, unter anderem aufgrund ihrer h ufig sehr intuitiven Bedienung (z.B. Computermaus, Lenkrad etc.) und der spielerischen Komponente, sowohl im medizinischen Bereich, als auch in der Entertainmentsparte vielversprechend.

Clinical applications of two-dimensional speckle tracking

Heart, 2011
To the Editor I read with interest Blessberger and Binder's article on the clinical applications of two dimensional speckle tracking following their excellent previous article detailing the technique's basic principles.1 2 The two articles carry significant detail but fall down in one major regard.

Phase-coupled two-dimensional speckle tracking algorithm

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2006
A new two-dimensional (2-D) speckle tracking method for displacement estimation based on the gradients of the magnitude and phase of 2-D complex correlation in a search region is presented. The novelty of this approach is that it couples the phase and magnitude gradients near the correlation peak to determine its coordinates with sub-sample accuracy in
