X-ray Fluorescence Computed Tomography (XFCT) Imaging with a Superfine Pencil Beam X-ray Source

open access: yesPhotonics, 2021
X-ray fluorescence computed tomography (XFCT) is a molecular imaging technique that can be used to sense different elements or nanoparticle (NP) agents inside deep samples or tissues. However, XFCT has not been a popular molecular imaging tool because it

X-Ray Fluorescence Computed Tomography With Polycapillary Focusing

open access: yesIEEE Access, 2014
Liposomal iodine nanoparticles (LINPs) have a long half-life and provide an excellent intravascular contrast. The nanoparticles can be functionalized as molecular probes for biological targets to facilitate numerous preclinical studies for translation ...

Adaptive zooming in X-ray computed tomography [PDF]

open access: yesJournal of X-Ray Science and Technology: Clinical Applications of Diagnosis and Therapeutics, 2014
BACKGROUND: In computed tomography (CT), the source-detector system commonly rotates around the object in a circular trajectory. Such a trajectory does not allow to exploit a detector fully when scanning elongated objects. OBJECTIVE: Increase the spatial resolution of the reconstructed image by optimal zooming during scanning.

High-throughput three-dimensional visualization of root system architecture of rice using X-ray computed tomography

open access: yesPlant Methods, 2019
Background X-ray computed tomography (CT) allows us to visualize root system architecture (RSA) beneath the soil, non-destructively and in a three-dimensional (3-D) form.

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 ...

Terahertz Computed Tomography of NASA Thermal Protection System Materials [PDF]

open access: yes, 2012
A terahertz axial computed tomography system has been developed that uses time domain measurements in order to form cross-sectional image slices and three-dimensional volume renderings of terahertz-transparent materials. The system can inspect samples as

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-Detector CT Findings of Typical and Atypical Appendicitis: A Pictorial Essay

open access: yesJournal of the Korean Society of Radiology, 2023
Multi-detector CT (MDCT) is a highly accurate diagnostic tool that is commonly used to evaluate appendicitis and its complications. The diagnosis of appendicitis based on MDCT findings can be difficult and challenging when the observed findings are ...
