Abstract: A method for detecting a fault in an energy supply network. State values are determined for a plurality of measuring points. The state values, which specify an electrical state of the energy supply network at the respective measuring point, are transmitted to a control center. The state values are used by an evaluation device for detecting a fault in the energy supply network. In order to detect errors in energy supply networks with low short-circuit currents with high reliability and selectivity, the evaluation device performs a state estimation, using a model description of the supply network suitable for describing possible electrical states of the energy supply network on the basis of state variables. The estimation examines whether an electrical state at least approximately matches the respective state values, can be described by the model description. If such a state is lacking, the evaluation device generates an fault detection signal.

Abstract: A method for reconstructing a three-dimensional image dataset from two-dimensional projection images includes recording the projection images using a collimator downstream of an X-ray source. A local Laplace filter is initially applied to the projection data of the projection images during the reconstruction using filtered back-projection. After this, high-frequency spikes arising in the Laplace-filtered projection data at boundaries to the image region are removed by a spike filter, and a global residual filter is applied. A fit parameter describing a fit function approximating the projection data characteristic in the uncorrected projection images inside the image region is determined based on at least marginal values of the projection data present at the boundaries. Next, following on from the use of the residual filter, an additive correction of the residual-filtered projection data in the image region is performed with the fit function scaled by a scaling factor.
