X-ray computed tomography device, has artifact determining unit determining target pixel as artifact, when each pixel lies above preset reference, and artifact reduction unit to effectuate imaging process for reduction of artifact on pixel

摘要

The device has an artifact determining unit (27-1) determining each pixel, which is contained in a tomography image, as an artifact. An artifact determining unit (27-2) presets a decision pixel range, which contains a target pixel. The unit (27-2) again determines the target pixel as the artifact, when each pixel, which is judged by the unit (27-1) as that pixel, at which the artifact can be generated, lies above a preset reference. An artifact reduction unit (25) is provided for the effectuation of an imaging process for the reduction of an artifact on each pixel. An independent claim is also included for a method for reducing artifacts in a tomography image.
