"A CT scanner is a rotating X-ray machine that usually bombards one X-ray wavelength," Antoine explains.
This target feature differs from standard rotating X-ray targets in conventional X-ray systems.
Essentially a rotating X-ray machine, a CT scanner takes many X-ray snapshots at different angles around a body part to produce a 3D image of its internal structure.
The latest machines are now the so-called multi-slice spiral (or helical) CTs based on a rotating X-ray source and an array of X-ray photon sensors on the opposite side of the CT gantry (Ulzheimer and Flohr, 2009).
Combining the high photon flux from a rotating anode X-ray tube with an X-ray optical component to focus and monochromatize the X-ray beam is the most promising instrumentation for best detection limits in the modern XRF laboratory.
ADXRD can give a very high angular resolution, but the standard approach of rotating the X-ray source and detector about the sample is impractical for most security-based scenarios.
CT scans that rotate an X-ray around the body to create a series of cross-sectional pictures can use 50 times more radiation than old-fashioned chest X-rays.
Posterior-anterior weight bearing knee radiographs were taken with the SynaFlex x ray positioning frame (Synarc, San Francisco, CA 29), with feet externally rotated 10° and knees and thighs touching the vertical platform anteriorly and the x ray beam angled 10° caudally.
Figure 2(a) shows examples of static and rotating anode TE X-ray sources.
Major trade-offs involving the rotating system, the X-ray system, and the detector package are also required.
SAXS experiments were carried out on an instrument with a high-intensity microfocus rotating Cu anode X-ray generator in the Laboratory for Advanced Studies of Membrane Proteins (Moscow Institute of Physics and Technology, Dolgoprudniy, Russia), using a standard transmission configuration.
