The interpolation of fourier transform data in tilted-view three-dimensional reconstruction

A method is described for interpolating the unevenly sampled Fourier transform data on lattice lines, collected during a tilted-view three-dimensional reconstruction of a plane lattice specimen, onto equally spaced sample points. The method performs local averaging of noisy data and inserts values into gaps in the data which are consistent with the spatial boundedness of the specimen. The method can be implemented computationally using a simple algorithm.
