1 Introduction As computed tomography (CT) systems have high spatial resolution, they are particularly useful in the diagnosis of stroke, damage to internal organs including the intracranial cavity, acute abdominal pain, as well as for cancer screening [ 1 , 2 , 3 , 4 , 5 ]. In recent years, use of multi-slice CT (MSCT) equipped with a multi-row detector has become widespread, and it is now possible to acquire thin slices in a short time. This has allowed inspection of the coronary arteries, colon, etc. with CT [ 6 , 7 , 8 , 9 ]. Moreover, with the development of

1 Overview Generally, the term X-ray designates a two-dimensional projection image of the material-dependent linear X-ray attenuation of a given object (radiography RT). In order to relate the physical content of this signal (density, material, shape) to three-dimensional object coordinates, RT is extended to “multi-view” radiography or Computed Tomography (CT). X-ray imaging is a widely used technique for non-destructive testing (NDT) and evaluation (NDE), for a detailed coverage of this application field refer to [ 1 ]. Images reveal spatial variations of

Reliable results require an effective artefact correction. In two earlier papers a Synchronous Arte- fact Correction (German: Einsatzsynchrone Artefakt-Reduktion EAR) was
