Speckle tracking strain echocardiography: What sonographers need to know!
Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2017 Introduction: Strain is a unitless measurement of dimensional or deformational change; speckle-tracking echocardiography is the most widely used technique to assess strain, with demonstrated clinical utility in a variety of settings.

Material characterization by laser speckle photometry
, 2022 Paper 841315The damage and stress conditions of large industrial components have to be tested continuously. Especially welding processes in the field of coal production demand a nondestructive monitoring of internal stresses under an external load.

X-ray Multimodal Intrinsic-Speckle-Tracking
, 2019 We develop X-ray Multi-modal Intrinsic-Speckle-Tracking (MIST), a form of X-ray speckle-tracking that is able to recover both the position-dependent phase shift and the position-dependent small-angle X-ray scattering (SAXS) signal of a phase object. MIST

Speckle spot detection in ultrasound images: Application to speckle reduction and speckle tracking [PDF]
2014 IEEE International Ultrasonics Symposium, 2014 This paper investigates the speckle spot detection task in ultrasound images. Speckle spots are described by structural criteria: dimensions, shape, and topology. We propose to represent the image using a morphological inclusion tree, from which speckle spots are detected using their structural appearance. This makes the method independent of contrast,

3D-based strain analysis and cardiotoxicity detection in cancer patients received chemotherapy
BMC Cancer, 2023 Background Chemotherapy-induced cardiotoxicity has become a prevalent complication. Regular monitoring of patients who received chemotherapy using 3D strain parameters may aid in early detection of myocardial damage and its prevention.
