X-ray induced acoustic computed tomography [PDF]

Photoacoustics, 2020
X-ray imaging has proved invaluable in medical diagnoses and non-destructive testing (NDT) in the past century. However, there remain two major limitations: radiation harm and inaccessibility to the sample.

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

PLoS 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.

Synchrotron‐source micro‐x‐ray computed tomography for examining butterfly eyes [PDF]

Ecology and Evolution
Comparative anatomy is an important tool for investigating evolutionary relationships among species, but the lack of scalable imaging tools and stains for rapidly mapping the microscale anatomies of related species poses a major impediment to using ...

Correlative single-cell hard X-ray computed tomography and X-ray fluorescence imaging [PDF]

Communications Biology
X-ray computed tomography (XCT) and X-ray fluorescence (XRF) imaging are two non-invasive imaging techniques to study cellular structures and chemical element distributions, respectively.

Optically‐Coupled X‐Ray Computed Laminography System for High‐Speed Inspection of Lithium‐Ion Batteries [PDF]

Advanced Science
Conventional X‐ray computed tomography systems for microstructure inspection typically employ a geometrically magnified imaging setup, requiring a micro‐focus X‐ray source to mitigate image blurring caused by a finite focal spot size. However, due to its

X-ray computed tomography [PDF]

Nature Reviews Methods Primers, 2021
X-ray computed tomography (CT) can reveal the internal details of objects in three dimensions non-destructively. In this Primer, we outline the basic principles of CT and describe the ways in which a CT scan can be acquired using X-ray tubes and synchrotron sources, including the different possible contrast modes that can be exploited.

Segmentation of pores in carbon fiber reinforced polymers using the U-Net convolutional neural network

Acta Polytechnica CTU Proceedings, 2023
This study demonstrates the utilization of deep learning techniques for binary semantic segmentation of pores in carbon fiber reinforced polymers (CFRP) using X-ray computed tomography (XCT) datasets.

Human Occupation of the North American Colorado Plateau ∼37,000 Years Ago

Frontiers in Ecology and Evolution, 2022
Calibrating human population dispersals across Earth’s surface is fundamental to assessing rates and timing of anthropogenic impacts and distinguishing ecological phenomena influenced by humans from those that were not.

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

Advanced 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.
