Three Dimensional Electrical Impedance Tomography [PDF]

open access: yes, 1996
The electrical resistivity of mammalian tissues varies widely and is correlated with physiological function. Electrical impedance tomography (EIT) can be used to probe such variations in vivo, and offers a non-invasive means of imaging the internal ...

Correlation Plenoptic Imaging With Entangled Photons

open access: yesTechnologies, 2016
Plenoptic imaging is a novel optical technique for three-dimensional imaging in a single shot. It is enabled by the simultaneous measurement of both the location and the propagation direction of light in a given scene.

Phaseless three-dimensional optical nano-imaging [PDF]

open access: yes, 2009
We propose a method for optical nano-imaging in which the structure of a three-dimensional inhomogeneous medium may be recovered from far-field power measurements.

Three‐dimensional decoupling imaging method for wideband two‐dimensional multiple‐input‐multiple‐output radar

open access: yesIET Radar, Sonar & Navigation, 2022
Wideband two‐dimensional multiple input multiple output (MIMO) radar can be used for target three‐dimensional (3‐D) imaging. As the echo of wideband MIMO radar is derived from both time and spatial sampling, the time‐frequency coupling is contained ...

Application of Three-Dimensional Technology for the Preoperative Evaluation of Retroperitoneal Tumors

open access: yesIEEE Access, 2019
With the development of computer medical imaging technology, three-dimensional technology has been gradually applied in medicine. We try to investigate the application value of 3D technology in the preoperative evaluation of retroperitoneal tumors.

Three dimensional imaging of short pulses

open access: yes, 2003
We exploit a slightly noncollinear second-harmonic cross-correlation scheme to map the 3D space-time intensity distribution of an unknown complex-shaped ultrashort optical pulse.

Observational Approaches to the Topology of the Universe [PDF]

open access: yes, 2000
Many different and complementary strategies for translating the basic principle of multiple topological imaging into observational analysis are now available, both for three-dimensional and two-dimensional catalogues.Comment: very compact, (2 page) write-
