A mode-locked laser, a rotating beam splitter, and a streak camera are the primary components of an imager with the ability to record three-dimensional images of remote (up to several kilometers) objects in real time in broad daylight. Immediate and future applications are noted.

Three-Dimensional Ultrasound Imaging
Annual Review of Biomedical Engineering, 2000▪ Abstract Two-dimensional viewing of three-dimensional anatomy by conventional ultrasound limits our ability to quantify and visualize a number of diseases and is partly responsible for the reported variability in diagnosis. Over the past two decades, many investigators have addressed this limitation by developing three-dimensional imaging ...

Three-dimensional ultrasound imaging
Current Opinion in Anaesthesiology, 2015Ultrasound guidance is frequently utilized for needle placement and observation of local anesthetic spread when performing peripheral nerve blocks. Although there is evidence that ultrasound technology can reduce complications, there are limitations to 2-dimensional (2-D) ultrasound. Three-dimensional (3-D) and especially real-time 3-D (4-D) ultrasound

Robotic Arm Based Automatic Ultrasound Scanning for Three-Dimensional Imaging
IEEE Transactions on Industrial Informatics, 2019This paper presents a human skin inspired automatic robotic ultrasound (US) system for three-dimensional (3-D) imaging. A depth camera was adopted to capture the point cloud of the skin surface.

Three-dimensional ultrasound imaging
Physics in Medicine and Biology, 2001Ultrasound is an inexpensive and widely used imaging modality for the diagnosis and staging of a number of diseases. In the past two decades, it has benefited from major advances in technology and has become an indispensable imaging modality, due to its flexibility and non-invasive character.

Three-dimensional ultrasound imaging
Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2010This review is about the development of three-dimensional (3D) ultrasonic medical imaging, how it works, and where its future lies. It assumes knowledge of two-dimensional (2D) ultrasound, which is covered elsewhere in this issue. The three main ways in which 3D ultrasound may be acquired are described: the mechanically swept 3D probe, the 2D ...

Since cells and tissues are inherently three-dimensional (3D), 3D imaging techniques are required to study them. 3D light microscopy offers a noninvasive, minimally destructive option for obtaining spatial and volumetric information about the structure and function of cells and tissues. 3D image data acquired with confocal or multiphoton microscopy can
