Analysis on Spectral Properties of Projection Signals in 3D Tomography.
In this paper a new approach is presented to analyze the spectral behavior of the 3D projection signal generated via plane integrals. More accurate determination of the effective support region of the projection spectrum without approximation is realized compared to previous approaches. On the basis of acquired results, a more accurate and optimal interlaced sampling pattern is correspondingly established. Compared to the traditional progressive sampling method, a reduction of sampling points by the factor 4 is achieved.
