Abstract
An industrial CT apparatus capable of obtaining a good image quality by a simple configuration. The apparatus is the second generating type incorporating the rotational motions as well as the traverse motions, in which the detector is positioned nearby a center of rotation of the object to be examined. When the object to be examined is a ring shaped object, the detector is positioned inside the center bore of the object. Also, the X-ray is emitted in a form of fan shaped beam whose symmetrical axis is deviated from an axial direction perpendicular to the traverse direction.
