Tomography of scaling [PDF]

open access: yesJournal of The Royal Society Interface, 2019
Scaling describes how a given quantity Y that characterizes a system varies with its size P . For most complex systems, it is of the form Y ∼ P β

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-

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.

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 ...

Doppler Tomography [PDF]

open access: yesAstrophysics and Space Science, 2005
I review the method of Doppler tomography which translates binary-star line profiles taken at a series of orbital phases into a distribution of emission over the binary. I begin with a discussion of the basic principles behind Doppler tomography, including a comparison of the relative merits of maximum entropy regularisation versus filtered back ...

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 ...
