ABSTRACT:
A CT system for cross-sectional imaging and a method using the same are involved. A second table for fine adjustment of an object is arranged on a conventional first table for the object. The center of gravity of a cross-sectional image of the object imaged in advance is determined, the object is finely moved by means of the second table such that the determined center of gravity coincides with the center or a corner of a mesh used for image formation, and cross-sectional imaging is again carried out. Through this, contrast at the edge of the object can be improved when the object is highly symmetrical as are many industrial products.
