ABSTRACT:
A provisional three-dimensional reconstruction of an examination object is determined based on two-dimensional original projection images. Provisional metal volumes are determined on the reconstruction by segmentation and mapped into the original projection images to define provisional metal areas. Edge points on edge zones of the provisional metal areas are selected. Data values of the original projection images within the provisional metal areas are modified as a function of data values of the selected edge points to determine modified projection images. Differential images are determined based on the original projection images and the corresponding modified projection images. Definitive metal areas are determined in the differential images by segmentation. The differential images are added to the modified projection images with the definitive metal areas deducted. A definitive three-dimensional reconstruction of the examination object is determined based on the modified projection images including the added differential images.
