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 ...

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.

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.

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.

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

X-ray induced acoustic computed tomography

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.
