Ultra high speed imaging of elasticity [PDF]
2002 IEEE Ultrasonics Symposium, 2002. Proceedings., 2003 Ultrafast ultrasonic imaging seems to have a strong potential for medical imaging applications. During the past five years, it has been applied successfully to quantitative assessment of soft tissues elasticity. An ultrafast ultrasonic scanner was built in our lab for quantitatively mapping the shear elasticity of soft tissues.

High-Speed Two-Photon Imaging [PDF]
Cold Spring Harbor Protocols, 2013 The small size of neuronal dendrites and spines combined with the high speed of neurophysiological signals, such as transients in membrane potential or ion concentration, necessitates that any functional study of these structures uses recording methods with both high spatial and high temporal resolutions.

Spectral imaging at high definition and high speed in the mid-infrared [PDF]
Science Advances, 2022 Spectral imaging in the mid-infrared (MIR) range provides simultaneous morphological and chemical information of a wide variety of samples. However, current MIR technologies struggle to produce high-definition images over a broad spectral range at acquisition rates that are compatible with real-time processes.

High speed multiphoton imaging [PDF]
SPIE Proceedings, 2016 Intravital multiphoton microscopy has emerged as a powerful technique to visualize cellular processes in-vivo. Real time processes revealed through live imaging provided many opportunities to capture cellular activities in living animals. The typical parameters that determine the performance of multiphoton microscopy are speed, field of view, 3D ...
