Computer tomography data processing system

摘要

The processing system provides weighting of randomly-distributed points within a frequency space, for effecting a 3-dimensional gridding algorithm for a 3-dimensional Fourier reconstruction of the computer tomograph. A 3-dimensional pre-gridding process is used to provide a real weighting cube, with the weightings for a subsequent weighting interpolation provided by the points of the weighting cube lying within a 3-dimensional interpolation window of the 3-dimensional gridding process.
