Intermediate spaces are computed by pre-processing the 2D (projection) and 3D (volume) image data. Webis explicitly based on Grangeat’s relation between the cone-beam and Radon transforms in R3 and the classical 3D Radon transform inversion. The main features of our approach can be summarized as follows: (1) The choice of a more general weight n(s;x;fi); (2) A novel way of dealing with disconti-

WebThe recent application of Fourier Based Iterative Reconstruction Method (FIRM) has made it possible to achieve high-quality 2D images from a fan beam Computed Tomography (CT) scan with a limited number of projections in a fast manner. The proposed methodology in this article is designed to provide 3D Radon space in linogram fashion to facilitate the … WebActually the relation we show reduces for m = 0andn = 3 to the well-known formula of Grangeat. In that sense, the paper contains a generalization of Grangeat’s formula to arbitrary tensor fields in any dimension.
