Ultrafast imaging of cell elasticity with optical microelastography [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance In wave physics, and especially seismology, uncorrelated vibrations could be exploited using “noise correlation” tools to reconstruct images of a medium. By using a high-frequency vibration, a high-speed tracking device, and a reconstruction

Diagnostic Performance of Real-Time Elastography in the Assessment of Advanced Fibrosis in Chronic Hepatitis C

GE: Portuguese Journal of Gastroenterology, 2016
Background and aims: Since liver fibrosis index (LFI) was developed by Fujimoto et al., real-time elastography (RTE) has become a promising non-invasive technique to assess fibrosis in chronic hepatitis C (CHC). The aims of this study were to compare the
