Interlaced X-ray diffraction computed tomography [PDF]

Journal of Applied Crystallography, 2016
An X-ray diffraction computed tomography data-collection strategy that allows, post experiment, a choice between temporal and spatial resolution is reported. This strategy enables time-resolved studies on comparatively short timescales, or alternatively allows for improved spatial resolution if the system under study, or components within it, appear to

Convolutional Neural Network Based Metal Artifact Reduction in X-Ray Computed Tomography [PDF]

IEEE Transactions on Medical Imaging, 2017
In the presence of metal implants, metal artifacts are introduced to x-ray computed tomography CT images. Although a large number of metal artifact reduction (MAR) methods have been proposed in the past decades, MAR is still one of the major problems in ...

In situ 3D characterization of fatigue cracks displacement fields [PDF]

Fracture and Structural Integrity, 2013
The three dimensional growth of fatigue cracks in samples of nodular graphite cast iron is characterized using laboratory X-ray computed tomography. The cracks grow from laser machined artificial defects, their development is monitored in situ using ...

Effects of X-Ray Dose On Rhizosphere Studies Using X-Ray Computed Tomography. [PDF]

PLoS ONE, 2013
X-ray Computed Tomography (CT) is a non-destructive imaging technique originally designed for diagnostic medicine, which was adopted for rhizosphere and soil science applications in the early 1980s.

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.

Review of high-speed imaging with lab-based x-ray computed tomography

Measurement science and technology, 2021
X-ray computed tomography (CT) is frequently used for non-destructive testing with many applications in a wide range of scientific research areas. The difference in imaging speeds between synchrotron and lab-based scanning has reduced as the capabilities

Reexamination of the mandibular and dental morphology of the Early Jurassic mammaliaform Hadrocodium wui [PDF]

Acta Palaeontologica Polonica, 2022
CT visualization of the mandible and dentition of Hadrocodium wui, a stem mammaliaform from the Lower Jurassic Lower Lufeng Formation of Yunnan, China has revealed new features not accessible by previous microscopic study of the fossil.

Potential of ultra-high-resolution photon-counting CT of bone metastases: initial experiences in breast cancer patients

npj Breast Cancer, 2021
Conventional CT scanners use energy-integrating detectors (EIDs). Photon-counting detector (PCD) computed tomography (CT) utilizes a CT detector technology based on smaller detector pixels capable of counting single photons and in addition discriminating
