Contactless inductive flow tomography [PDF]

open access: yes, 2004
The three-dimensional velocity field of a propeller driven liquid metal flow is reconstructed by a contactless inductive flow tomography (CIFT). The underlying theory is presented within the framework of an integral equation system that governs the ...

On the meaning and interpretation of Tomography in abstract Hilbert spaces [PDF]

open access: yes, 2005
The mechanism of describing quantum states by standard probability (tomographic one) instead of wave function or density matrix is elucidated.

Electron tomography

open access: yesMaterials Today, 2004
Electron tomography is a mature 3D nanocharacterisation technique with applications to almost all classes of materials. It offers 3D resolution at the nanometre level, or better, in volumes of a few hundred nanometres—precisely the playground of the nanoscientist.

All fiber polarization insensitive detection for spectrometer based optical coherence tomography using optical switch

open access: yes, 2019
Polarization dependent image artifacts are common in optical coherence tomography imaging. Polarization insensitive detection scheme for swept source based optical coherence tomography systems is well established but is yet to be demonstrated for all ...

Quantum Tomography twenty years later

open access: yes, 2015
A sample of some relevant developments that have taken place during the last twenty years in classical and quantum tomography are displayed. We will present a general conceptual framework that provides a simple unifying mathematical picture for all of ...

A mathematical model and inversion procedure for Magneto-Acousto-Electric Tomography (MAET)

open access: yes, 2011
Magneto-Acousto-Electric Tomography (MAET), also known as the Lorentz force or Hall effect tomography, is a novel hybrid modality designed to be a high-resolution alternative to the unstable Electrical Impedance Tomography.

Computed tomography-osteoaboorptiometry [PDF]

open access: yes, 1990
A method of making a visual display of subchondral mineralization in the major synovial joints is described. Unlike existing procedures, it can be used on the living subject. A modified application of computed tomography-densitometry, computed tomography-
