Anisotropic Elastography for Local Passive Properties and Active Contractility of Myocardium from Dynamic Heart Imaging Sequence

open access: yesInternational Journal of Biomedical Imaging, 2006
Major heart diseases such as ischemia and hypertrophic myocardiopathy are accompanied with significant changes in the passive mechanical properties and active contractility of myocardium.

Investigating plywood behaviour in outdoor conditions [PDF]

open access: yes, 2016
Moisture behaviour of plywood is investigated in combination with detailed structural analysis. In the lab, neutron radiography and X-ray computed tomography (X-ray CT) were used to map the moisture distribution and internal structure of plywood ...

Multi-Mounted X-Ray Computed Tomography. [PDF]

open access: yesPLoS ONE, 2016
Most existing X-ray computed tomography (CT) techniques work in single-mounted mode and need to scan the inspected objects one by one. It is time-consuming and not acceptable for the inspection in a large scale.

X-ray luminescence computed tomography using a focused X-ray beam

open access: yes, 2017
Due to the low X-ray photon utilization efficiency and low measurement sensitivity of the electron multiplying charge coupled device (EMCCD) camera setup, the collimator based narrow beam X-ray luminescence computed tomography (XLCT) usually requires a ...

Algorithms for joint activity–attenuation estimation from positron emission tomography scatter

open access: yesEJNMMI Physics, 2019
Background Attenuation correction in positron emission tomography remains challenging in the absence of measured transmission data. Scattered emission data may contribute missing information, but quantitative scatter-to-attenuation (S2A) reconstruction ...

A comparative study of optical properties and X-ray induced luminescence of octahedral molybdenum and tungsten cluster complexes [PDF]

open access: yes, 2017
© 2017 The Royal Society of Chemistry. Octahedral metal cluster complexes have high potential for biomedical applications. In order to evaluate the benefits of these moieties for combined CT/X-ray luminescence computed tomography, this paper compares ...

X‐ray Stain Localization with Near‐Field Ptychographic Computed Tomography

open access: yesAdvanced Science, 2022
Although X‐ray contrast agents offer specific characteristics in terms of targeting and attenuation, their accumulation in the tissue on a cellular level is usually not known and difficult to access, as it requires high resolution and sensitivity.

Fluorescent scanning x-ray tomography with synchrotron radiation [PDF]

open access: yes, 1995
Fluorescent scanning (FS) x-ray tomography was developed to detect nonradioactive tracer materials (iodine and gadolinium) in a living object. FS x-ray tomography consists of a silicon (111) channel cut monochromator, an x-ray shutter, an x-ray slit ...
