background and aims. at present, cone beam computed tomography (cbct) has become a substitute for computed tomography (ct) in dental procedures. the metallic materials used in dentistry can produce artifacts due to the beam hardening phenomenon. these artifacts decrease the quality of images. in the present study, the number of artifacts as a result of beam hardening in the images of dental imp...

X-ray Computed Tomography (XCT) has become a common tool for dimensional analysis as it allows non-destructive internal and external measurements. Manufacturers often specify the accuracy of dedicated metrology XCT systems maximum permissible error ( MPE ) statement determined using workpieces, test lengths positions that are significantly different between manufacturers. The VDI/VDE 2630-1.3:2...
