Abstract:
1. A method for reconstruction of a 3D volume from recorded projection images, wherein the method comprises the following steps: a) providing a set of recorded projection images that have been recorded with a tomography apparatus using penetrating radiation; b) providing values of at least two parameters; c) reconstructing the 3D volume from the set of recorded projection images, thereby using the values of the at least two parameters; d) generating simulated projection images, wherein each simulated projection image corresponds to one of the recorded projection images, by simulating projections of the penetrating radiation through the reconstructed 3D volume, thereby using the values of the at least two parameters; e) determining a re-projection error by comparing the simulated projection images with the corresponding recorded projection images; f) changing the values of the at least two parameters, thereby taking into account the interdependence of the at least two parameters, and repeating the steps c) to f) until the re-projection error is minimized; wherein the method is used in the field of dental medical applications.
