Apparatus for computerized tomography, method of same, and apparatus for computerized tomography scanning

摘要

With the apparatus of CT, if the object contains a foreign body having high spatial frequency component such as a polygonal body etc., and large density difference from another region, a radial artifact is generated from a corner part of the side. The first object of the present invention is to provide an apparatus of CT to reduce artifacts without lowering of spatial resolving power. The second object of the present invention is to provide an apparatus of CT to reduce artifacts without increasing scanning time so much. The objects described above are achieved by the present invention with a method to disperse penetration data to surroundings when a sudden changing part of penetration data in translational data is detected in collecting penetration data from every direction for reconstruction of an image.
