    摘要: A tomographic apparatus of this invention includes a dividing unit for dividing a sectional image into a pixel group including artifacts and a pixel group not including artifacts by carrying out an independent component analysis (ICA) of the artifacts, and a pixel group processing unit for applying a smoothing filter as a predetermined process relating to correction only with respect to the above pixel group including the artifacts, whereby a correction process is carried out to remove the artifacts. Thus, the artifacts can be removed stably.
