Red Blood Cells as Endogenous Biotweezers for Optical Micromanipulation In Vivo
Advanced Science, EarlyView.By synergistically integrating the long‐distance manipulation fiber probe (LDMFP) and endogenous red blood cells (RBCs) as biocompatible optical elements, a natural RBC biotweezer was developed for the desired microparticle manipulation and immune cell activation within living vasculature, which might offer an alternative tool for intravital optical ...

Surface and Interfacial Engineering toward Durable Mechanically Coupled Flexible Electronics
Advanced Science, EarlyView.This Review highlights how surface and interfacial engineering governs the reliability, durability, and functional stability of mechanically coupled flexible electronics. By integrating fundamental interfacial theory, failure mechanisms, multiscale engineering strategies, and representative applications, it provides a design‐oriented framework for ...

In this work we present a new hybrid imaging technique that combines electrical impedance tomography (EIT) with acoustic tomography. The novel technique makes use of the fact that the absorbed electrical energy inside the body raises its temperature, thus leading to expansion effects.

Computed Tomography of Acoustic Neuroma
Radiology, 1977Review of computed tomographic (CT) scans of 49 consecutive patients with surgically excised acoustic neuromas revealed positive scans in 80% following contrast enhancement, with 20% false negative scans. All tumors over 2 cm in diameter were shown by optimal scans with contrast enhancement.

Computed Tomography of Acoustic Neurinoma
Radiology, 1978Thirty-seven patients with 39 acoustic neurinomas were studied with computed tomography (CT). Six tumors (15%) were seen on the nonenhanced scans and infusion of contrast material demonstrated 23 more tumors. Ten tumors (26%) were not seen as soft-tissue masses on the enhanced CT scans.

Array for acoustic tomography of the atmosphere
IEEE International Geoscience and Remote Sensing Symposium, 2003Tomography has been widely used in many fields of science, medicine and technology for remote sensing of different media. Acoustic tomography of the atmosphere allows one to reconstruct the three-dimensional temperature and velocity fields and to monitor their evolution in time. It was first employed in the 1990s.

Acoustic tomography of the atmosphere
IGARSS 2000. IEEE 2000 International Geoscience and Remote Sensing Symposium. Taking the Pulse of the Planet: The Role of Remote Sensing in Managing the Environment. Proceedings (Cat. No.00CH37120), 2002Sodar and RASS are examples of remote sensing techniques used widely around the world today which are based on acoustic propagation and scattering. Acoustic tomography of the atmosphere, in comparison, has been used to a much lesser extent. However, acoustic tomography will probably be used more in the atmosphere in coming years.

Ocean acoustic reverberation tomography
The Journal of the Acoustical Society of America, 2015Seismic wide-angle imaging using ship-towed acoustic sources and networks of ocean bottom seismographs is a common technique for exploring earth structure beneath the oceans. In these studies, the recorded data are dominated by acoustic waves propagating as reverberations in the water column.

Acoustic telemetry for ocean acoustic tomography
IEEE Journal of Oceanic Engineering, 1984Very low data rate burst telemetry for long-range deep-ocean applications is discussed. Energy efficiency, propagation coherence, and waveform coding, together with transmitter constraints, influenced the design of proposed buoy-to-buoy and buoy-to-shore systems.
