Speckle tracking approaches in speckle sensing [PDF]
SPIE Proceedings, 2017 This paper reports some initial investigations into the application of feature tracking algorithms as an alternative data processing method for speckle correlation sensors capable of determining both the speckle pattern translation and rotation. The accuracy of translation measurements using the feature tracking approach was found to be similar to that

Speckle Tracking and Transthyretin Amyloid Cardiomyopathy
Arquivos Brasileiros de Cardiologia, 2016 Background: Amyloidosis is a disease caused by deposits of insoluble fibrils in extracellular spaces. The most common type of familial amyloidosis is mediated by mutation of transthyretin, especially Val30Met.

Speckle tracking ultrasonography as a new tool to assess diaphragmatic function: a feasibility study [PDF]
Ultrasonography, 2022 A reliable method of measuring diaphragmatic function at the bedside is still lacking. Widely used two-dimensional (2D) ultrasonographic measurements, such as diaphragm excursion, diaphragm thickness, and fractional thickening (FT) have failed to show ...

speckle-tracking: a software suite for ptychographic X-ray speckle tracking [PDF]
Journal of Applied Crystallography, 2020 In recent years, X-ray speckle-tracking techniques have emerged as viable tools for wavefront metrology and sample imaging applications. These methods are based on the measurement of near-field images. Thanks to their simple experimental setup, high angular sensitivity and compatibility with low-coherence sources, these methods have been actively ...

Using TAPSE versus speckle tracking in assessment of right ventricular function in healthy heavy chronic cigarette smokers [PDF]
Al-Azhar International Medical Journal, 2022 Background Smoking increases risks of cardiovascular mortality and morbidity by multiple potential mechanisms. The right ventricle hasn’t been well studied in the healthy heavy smokers’ population in which chest causes of right ventricle dysfunction hasn’

Ptychographic X-ray speckle tracking [PDF]
Journal of Applied Crystallography, 2020 A method is presented for the measurement of the phase gradient of a wavefront by tracking the relative motion of speckles in projection holograms as a sample is scanned across the wavefront. By removing the need to obtain an undistorted reference image of the sample, this method is suitable for the metrology of highly divergent wavefields.
