WebOct 18, 2006 · Actually the relation we show reduces for m = 0 and n = 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. WebGrangeat's relation in cone beam CT.

WebWe used consistency conditions derived from Grangeat's fundamental relation between cone beam projection data and 3-D Radon transform. The optimal polynomial … WebDownload scientific diagram (a) Principal algorithm flow of the Grangeat-based 2D/3D registration. Intermediate spaces are computed by pre-processing the 2D (projection) and 3D (volume) image data. WebFor this reason, in the first phase, the 3D Radon space is generated using CBP data after discretization and optimization of the famous Grangeat's formula. The method used in this process involves fast Pseudo Polar Fourier transform (PPFT) based on 2D and 3D Discrete Radon Transformation (DRT) algorithms with no wraparound effects. sonoff 3 teclas
