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

Quantification of Renal Stone Contrast with Ultrasound in Human Subjects [PDF]
, 2017 Purpose: Greater visual contrast between calculi and tissue would improve ultrasound (US) imaging of urolithiasis and potentially expand clinical use. The color Doppler twinkling artifact has been suggested to provide enhanced contrast of stones compared

Monitoring kidney optical properties during cold storage preservation with spatial frequency domain imaging. [PDF]
, 2019 Transplantation of kidneys results in delayed graft function in as many as 40% of cases. During the organ transplantation process, donor kidneys undergo a period of cold ischemic time (CIT), where the organ is preserved with a cold storage solution to ...

One year in review: ultrasound in arthritis [PDF]
, 2016 Musculoskeletal ultrasound (MSUS) has become a relevant part of rheumatology practice and research because it substantially allows us to optimize management of rheumatic and musculoskeletal diseases. This non-invasive imaging modality is a valuable point-

Assessment of Regional Myocardial Displacement via Spectral Tissue Doppler Compared with Color Tissue Tracking [PDF]
Journal of Tehran University Heart Center, 2008 Background: The recent developments in tissue Doppler imaging (TDI) now more than ever permit the quantification of the myocardial function. In the current systems, tissue tracking or displacement curves are generated from color tissue Doppler data ...

ASSESSMENT OF LEFT VENTRICULAR FUNCTION USING TISSUE DOPPLER IMAGING
Zdravniški Vestnik, 2004 Background. Objective evidence of cardiac dysfunction is one of the diagnostic criteria for heart failure. It is often hard to assess systolic function and assessing diastolic dysfunction is even harder because there are no generally accepted ...

Effect of arrhythmias on tissue Doppler velocities
Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2018 Sa wave of tissue Doppler imaging correlates with ventricular systole (QRS-T of electrocardiogram). Ea wave correlates with ventricular filling in early diastole. Aa wave correlates with ventricular filling during atrial contraction and correlates with P
