摘要: The invention relates to an apparatus and a method for the processing of reconstructed 3D images (I) in C-arm based volume imaging which often exhibit spatially slowly varying inhomogeneities caused by inconsistent projection data. To correct (I), retrospective homogenization procedure is proposed. image segmented (11, 12) into principal classes like bone, tissue air on their gray values. Only tissue-regions (M) are then used as support order fit (14) 2D baseline (B) representing smooth shape cupping or other inhomogeneities. Finally inverse estimated subtracted from original slice
