A method for reconstruction of a two-dimensional sectional image corresponding to a sectional plane through a recorded object from two-dimensional projection images recorded along a recording trajectory at different projection angles with an X-ray device is proposed. The sectional plane having at least two intersection points with the imaging trajectory is selected. After selection of the sectional plane, an intermediate function on the sectional plane is determined by backprojection of the projection images processed with a differentiation filter. The object densities forming the sectional image are determined from the intermediate function by a two-dimensional iterative deconvolution method.
