Evaluation of right ventricular function performed by 3d-echocardiography in scleroderma patients [PDF]

open access: yes, 2015
The impairment of the right ventricle (RV) in systemic sclerosis (SSc) is usually related to pulmonary arterial hypertension (PAH). New echocardiographic techniques, such as 3-dimensional echocardiography (3DE) and 2-dimensional speckle tracking (2DSTE),

Validated Ultrasound Speckle Tracking Method for Measuring Strains of Knee Collateral Ligaments In-Situ during Varus/Valgus Loading

open access: yesSensors, 2021
Current ultrasound techniques face several challenges to measure strains when translated from large tendon to in-situ knee collateral ligament applications, despite the potential to reduce knee arthroplasty failures attributed to ligament imbalance ...

Speckle-tracking echocardiography combined with imaging mass spectrometry assesses region-dependent alterations [PDF]

open access: yes, 2020
Left ventricular (LV) contraction is characterized by shortening and thickening of longitudinal and circumferential fibres. To date, it is poorly understood how LV deformation is altered in the pathogenesis of streptozotocin (STZ)-induced type 1 diabetes

Speckle tracking accuracy enhancement by temporal super-resolution of three-dimensional echocardiography images

open access: yesJournal of Medical Signals and Sensors, 2021
Background: Speckle tracking has always been a challenging issue in echocardiography images due to the lowcontrast and noisy nature of ultrasonic imaging modality. While in ultrasound imaging, framerate is limited by image size and sound speed in tissue,

Continuous ultrasound speckle tracking with Gaussian mixtures [PDF]

open access: yes2015 37th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2015
Speckle tracking echocardiography (STE) is now widely used for measuring strain, deformations, and motion in cardiology. STE involves three successive steps: acquisition of individual frames, speckle detection, and image registration using speckles as landmarks.

Speckle tracking strain echocardiography: What sonographers need to know!

open access: yesJournal 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.

3D-based strain analysis and cardiotoxicity detection in cancer patients received chemotherapy

open access: yesBMC 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.

Modern optical astronomy: technology and impact of interferometry [PDF]

open access: yes, 2002
The present `state of the art' and the path to future progress in high spatial resolution imaging interferometry is reviewed. The review begins with a treatment of the fundamentals of stellar optical interferometry, the origin, properties, optical ...

Prognostic implications of left ventricular global longitudinal strain in heart failure patients with narrow QRS complex treated with cardiac resynchronization therapy: a subanalysis of the randomized EchoCRT trial [PDF]

open access: yes, 2016
Aim: Left ventricular (LV) global longitudinal strain (GLS) reflects LV systolic function and correlates inversely with the extent of LV myocardial scar and fibrosis.
