Three-dimensional speckle tracking

Current Cardiovascular Imaging Reports, 2008
Two-dimensional speckle tracking is a useful technology. Nevertheless, it has some limitations because the heart has three dimensions. The recent development of three-dimensional speckle tracking technology provides a new diagnostic tool. By using this new method, a more complete and probably accurate evaluation of global and segmental left ventricular

Speckle tracking echocardiography in acute myocarditis

The International Journal of Cardiovascular Imaging, 2012
To evaluate 2-dimensional speckle tracking echocardiography as a diagnostic and prognostic tool in patients with acute myocarditis. In this retrospective cohort study, 45 patients (age, 39 ± 15 years; 32 male) with suspected acute myocarditis and 83 healthy controls (age, 39 ± 13 years; 27 male) underwent 2-dimensional speckle tracking echocardiography.

3-D Correlation-Based Speckle Tracking

Ultrasonic Imaging, 2005
Widely-used 1-D/2-D speckle tracking techniques in elasticity imaging often experience significant speckle decorrelation in applications involving large elevational motion (i.e., out of plane motion). The problem is more pronounced for cardiac strain rate imaging (SRI) since it is very difficult to confine cardiac motion to a single image plane. Here,

Diagnostic Possibilities of Speckle-Tracking Echocardiography

Kardiologiia, 2016
The review is devoted to merits and demerits of a new method of assessment of condition of the heart - speckle-tracking echocardiography. Speckle-tracking echocardiography is a perspective method allowing to register disorders of both global and regional contractile motion.

Nonlocal means filter-based speckle tracking

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2015
The objective of sensorless freehand 3-D ultrasound imaging is to eliminate the need for additional tracking hardware and reduce cost and complexity. However, the accuracy of current out-of-plane pose estimation is main obstacle for full 6-degree-of-freedom (DoF) tracking.

Speckle Mitigation for Optical Tracking

2020 IEEE Aerospace Conference, 2020
Optical tracking systems encounter a number of challenges, including turbulence and speckle. Atmospheric turbulence causes phase perturbations that distort the track imagery. Additionally, natural illumination of the object is sometimes insufficient, and the tracking system must illuminate the object with a laser.
