X-ray computed tomography in life sciences

open access: yesBMC Biology, 2020
Recent developments within micro-computed tomography (μCT) imaging have combined to extend our capacity to image tissue in three (3D) and four (4D) dimensions at micron and sub-micron spatial resolutions, opening the way for virtual histology, live cell ...

X-ray-Computed Tomography Contrast Agents [PDF]

open access: yesChemical Reviews, 2012
X-ray computed tomography (CT) is a well-established tissue imaging technique employed in a variety of research and clinical settings.1 Specifically, CT is a non-invasive clinical diagnostic tool that allows for 3D visual reconstruction and segmentation of tissues of interest. High resolution CT systems can be used to perform non-destructive 3D imaging

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

open access: yesIEEE 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 ...

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

open access: yesAdvanced 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.

Algorithms for joint activity–attenuation estimation from positron emission tomography scatter

open access: yesEJNMMI Physics, 2019
Background Attenuation correction in positron emission tomography remains challenging in the absence of measured transmission data. Scattered emission data may contribute missing information, but quantitative scatter-to-attenuation (S2A) reconstruction ...
