Interpretation of Annular Tissue Doppler Imaging [PDF]

open access: yesKorean Circulation Journal, 2011
Refer to the page 137-142 Diastolic dysfunction has become a more predominant form of heart failure (HF) than systolic dysfunction in the community. However, diastolic dysfunction is not always related to HF. Diastolic HF is defined as HF with preserved left ventricular (LV) systolic function, usually a LV ejection fraction (EF) of more than 50%, in

Tissue Doppler Imaging: An Overview

open access: yes, 2021
Tissue Doppler Imaging (TDI) is a non-invasive, echocardiographic imaging technique that measures myocardial motion velocity throughout the cardiac cycle using Doppler principles. While conventional Doppler techniques assess blood flow velocity by sensing high-frequency, low amplitude signals from small, fast-moving blood cells, TDI uses the same ...

Time-of-flight resolved light field fluctuations reveal deep human tissue physiology. [PDF]

open access: yes, 2020
Red blood cells (RBCs) transport oxygen to tissues and remove carbon dioxide. Diffuse optical flowmetry (DOF) assesses deep tissue RBC dynamics by measuring coherent fluctuations of multiply scattered near-infrared light intensity.

Assessing the performance of ultrafast vector flow imaging in the neonatal heart via multiphysics modeling and In vitro experiments [PDF]

open access: yes, 2016
Ultrafast vector flow imaging would benefit newborn patients with congenital heart disorders, but still requires thorough validation before translation to clinical practice. This paper investigates 2-D speckle tracking (ST) of intraventricular blood flow
