Effect of X‐Ray Computed Tomography Imaging Parameters on Quantification of Petrophysical Properties

open access: yesEarth and Space Science, 2023
Three‐dimensional (3D) X‐ray computed tomography (X‐ray CT) imaging has emerged as a nondestructive means of microstructural characterization. However, obtaining and processing high‐quality and high‐resolution images is time‐consuming and often requires ...

The Effect of Fiber Architecture on the Conductance of Inkjet Printed Ag on Electronic Textile Substrates

open access: yesSmall Structures
A nanoparticle Ag ink has been inkjet printed on six different plain‐weave polyester textile substrates without any further surface treatment. They are manufactured from the same composition of polyester fibers but with different fiber diameters and yarn

Dark-field chest x-ray imaging: first experience in patients with alpha1-antitrypsin deficiency

open access: yesEuropean Radiology Experimental, 2022
Background Spirometry and conventional chest x-ray have limitations in investigating early emphysema, while computed tomography, the reference imaging method in this context, is not part of routine patient care due to its higher radiation dose.

Maximizing temperature sensitivity in a one-dimensional photonic crystal thermal sensor

open access: yesScientific Reports
This paper focuses on a defective one-dimensional photonic crystal thermal sensor with fabricated layers of gallium nitride, glycerin, and air. The transmission features of this sensor have been presented based on the transfer matrix approach using ...

High‐quality X‐ray computed tomography reconstruction using projected and interpolated images

open access: yesIET Image Processing, 2019
Recent advances in computation power have allowed computed tomography (CT) to utilise iterative reconstruction (IR) algorithms. The IR technique can handle noisy data and reconstructs optimal CT images from limited projected images.

Ring artifacts removal in X-ray-induced acoustic computed tomography

open access: yesJournal of Innovative Optical Health Sciences, 2022
X-ray-induced acoustic computed tomography (XACT) is a hybrid imaging modality for detecting X-ray absorption distribution via ultrasound emission. It facilitates imaging from a single projection X-ray illumination, thus reducing the radiation exposure ...

X-ray computed tomography investigations of Cucuteni ceramic statuettes

open access: yesDocumenta Praehistorica, 2013
Deciphering the internal structure of prehistoric artefacts can provide spectacular insights that might help us understand the people who made them. In order to preserve the integrity of these relics of past civilisations, it is desirable to make such ...
