The effect of focal spot size on the spatial resolution of variable resolution X-ray CT scanner
Background: A variable resolution X-ray (VRX) CT scanner provides a great increase in the spatial resolution. In VRX CT scanners, the spatial resolution of the system and its field of view (FOV) can be changed according to the object size. One of the main factors that limit the spatial resolution of VRX CT scanner is the effect of the X-ray focal spot. Materials and Methods: A theoreti...
متن کاملMicrobeam high-resolution diffraction and x-ray standing wave methods applied to semiconductor structures
A new approach to conditioning x-ray microbeams for high angular resolution x-ray diffraction and scattering techniques is introduced. We combined focusing optics (one-bounce imaging capillary) and post-focusing collimating optics (miniature Si(004) channel-cut crystal) to generate an x-ray microbeam with a size of 10μm and ultimate angular resolution of 14μrad. The microbeam was used to analys...

متن کاملScattering: X-Ray Standing Wave Techniques
Introduction The X-ray standing wave (XSW) technique provides an element-specific structural probe by using x-ray reflectivity to generate a " two-beam " interference field that in turn induces a spatial dependence to the x-ray spectroscopic yields from atoms within the field. The XSW technique is primarily used for resolving the atomic-scale structure at surfaces, interfaces, and thin films wi...
