Abstract
Recently we proposed a 3D reconstruction algorithm based on Fourier analysis using Cartesian coordinates. In this algorithm the computations to determine the values of the 3D Discrete Fourier Transform of the density of an asymmetric object could be naturally distributed over the nodes of a parallel system. Now we present an improvement of this algorithm which, for reconstruction at points of an N × N × N grid, uses O(N 3) arithmetic operations instead of O(N 5). The algorithm is general and can be used for 3D reconstruction of asymmetric objects for applications other than structural biology.
