Tissue-Integrating Oxygen Sensors: Continuous Tracking of Tissue Hypoxia [PDF]
, 2017 We describe a simple method of tracking oxygen in real-time with injectable, tissue-integrating microsensors. The sensors are small (500 μm × 500 μm × 5 mm), soft, flexible, tissue-like, biocompatible hydrogel s that have been shown to overcome the foreign body response for long-term sensing.

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 ...

Quantifying left atrial structure and function using single-plane tissue-tracking cardiac magnetic resonance. [PDF]
Magn Reson Imaging, 2017 Purpose Left atrial (LA) structure and function are important markers of adverse cardiovascular outcomes. Tissue-tracking cardiovascular magnetic resonance (CMR) accurately quantifies LA volume, strain, and strain rate based on biplane long-axis imaging.
