Three-dimensional imaging of dislocations [PDF]

open access: yesNature, 2013
arising from C.-C. Chen et al. , 74–77 (2013)10.1038/nature12009 At first sight, the achievement of determining atom positions in three dimensions appears spectacular1. Chen and colleagues1 apply a form of tomographic reconstruction to a tilt series of annular dark field (ADF) images of crystalline ...

Discrete Imaging Models for Three-Dimensional Optoacoustic Tomography using Radially Symmetric Expansion Functions [PDF]

open access: yes, 2014
Optoacoustic tomography (OAT), also known as photoacoustic tomography, is an emerging computed biomedical imaging modality that exploits optical contrast and ultrasonic detection principles.

Differential Photoelectron Holography: A New Approach for Three-Dimensional Atomic Imaging

open access: yes, 2003
We propose differential holography as a method to overcome the long-standing forward-scattering problem in photoelectron holography and related techniques for the three-dimensional imaging of atoms.

A planar magneto-inductive lens for three-dimensional subwavelength imaging [PDF]

open access: yes, 2005
A planar near-field magnetoinductive lens operating in the microwave range is presented. The proposed device consists of two parallel planar arrays of metallic broadside coupled (BC-) split ring resonators (SRRs), or BC-SRRs.

Photon counting compressive depth mapping [PDF]

open access: yes, 2013
We demonstrate a compressed sensing, photon counting lidar system based on the single-pixel camera. Our technique recovers both depth and intensity maps from a single under-sampled set of incoherent, linear projections of a scene of interest at ultra-low

Three-dimensional Imaging of Microstructure in Gold Nanocrystals [PDF]

open access: yes, 2003
X-ray diffraction using a coherent beam involves the mutual interference among all the extremities of small crystals. The continuous diffraction pattern so produced can be phased because it can be oversampled.

Three-dimensional digitalized virtual planning for saphenous artery flap: a pilot study

open access: yesComputer Assisted Surgery, 2016
Objective: Since the 1970s, research and applications on flap and muscle flap had solved many problems in microsurgical reconstruction. However, the traditional flap design is completely dependent on two-dimensional (2D) images. The purpose of this study
