X-raysINTENSIVE care unitsX-ray detectionTOMOGRAPHYBackground: A CT scanner makes many measurements, from different rotational angles, of X-ray attenuation (weakening in force or intensity) through the cross-sectional plane of the thorax. It then uses these data to reconst...
Computed tomography (CT) systems use a series of X-ray images to create an image volume dataset with slices that can be manipulated on any plane using advanced visualization software. The section includes computed tomography scanners, CT contrast agents,

X-ray-computed tomography (CT) is a well-established tissue imaging technique employed in a variety of research and clinical settings. Specifically, CT is a noninvasive clinical diagnostic tool that allows for 3D visual reconstruction and segmentation of tissues of interest. A series of attenuation...
New types of X-ray computed tomography (CT), fluorescent X-ray CT and phase-contrast X-ray CT are being developed for biomedical research. While fluorescent scanning X-ray CT (FXCT) can detect specific contrast elements, or endogenous iodine, at very low content (less than 400 pg iodine ...
With X-Ray Diffraction Computed Tomography (XRD-CT), phases within a mixture or bulk can be identified, associated with their position within the sample, and monitored in real time. One key to making this process work is a high-energy, hybrid-pixel detector. ...

Our aim was to answer questions related to the effect of inter- vs. intra-specific interactions on the growth and utilization of undisturbed space by fine roots within three dimensions (3D) using micro X-ray computed tomography. To achieve this, Populus tremuloides (quaking aspen) and Picea ...
