X-ray diffraction studies of illite/smectite from rocks, <1 mu m randomly oriented powders, and <1 mu m oriented powder aggregates; the absence of laboratory-induced artifacts X-ray diffraction patterns were obtained from rock fragments, < 1 mum randomly oriented freeze-dried powders, and < ...
In our paper we will demonstrate how we have successfully used, readily available standard Medical X-Ray Computed Tomography (CT), in scanning clay and ceramic artifacts. Till now, we have used CT in our studies of ceramic technology, conservation and restoration. Other researchers have used CT...

摘要: Focuses on a high-resolution two-dimensional fan-beam computed tomography (CT) simulator used in identifying the cause of metal streak artifacts X-ray CT. Validation of the simulator; Exponential edge-gradient effect; Error due to noise determined from simulations with and without noise....
Interpretation of X-ray fluorescence images of archeological artifacts is complicated by the presence of surface relief and roughness. Using two symmetrically arranged fluorescence detectors in a back-reflection geometry, the proper X-ray fluorescence yield can be distinguished from intensity variations caus...
The lead foil of dental x-ray film packets may cause a number of artifacts; especially well known are the "tractor treads" and "herringbone patterns" following a backward filmpositioning in the patient's mouth. In the present paper a specific and seldomly occurring lead foil artifact is descri...
For example, for reconstruction of an edge at least one X-ray has to be tangential to the edge4. Furthermore, image quality can be severely reduced by artifacts due to beam-hardening and high attenuation materials. Typically it is not possible to avoid such artifacts completely, but one can...

But his name is synonymous with the Andrea Doria wreck, on which he made over 120 dives in the '80s and ‘90s, salvaging artifacts, and conducted in-depth research. In this interview by Andrea Murdock Alpini, we gain insight into his life and deep relationship with the Andrea Doria. ...
