Grangeat’s relation

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. We further briefly explain the importance of that formula for the problem of tensor field tomography. 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-
