Approximate Reconstruction Formulae for the Cone Beam Transform I (an Unpublished Manuscript from November 1987)
نویسنده
چکیده
In this paper we present a method for deriving approximate inversion formulae for the divergent beam x-ray transform in three-space when the source set is a curve. When the source set is a planar convex curve, we obtain new approximate inversion formulae which are quasi-local. Finally we compare these methods with existing convolutionbackprojection algorithms for 3-D reconstruction. * Supported in part by NSF Grants DMS–8301691–01, DMS–880591.

Exact Reconstruction From Uniformly Attenuated Helical Cone-Beam Projections in SPECT
In recent years the development of cone-beam reconstruction algorithms has been an active research area in x-ray computed tomography (CT), and significant progress has been made in the advancement of algorithms. Theoretically exact and computationally efficient analytical algorithms can be found in the literature. However, in single photon emission computed tomography (SPECT), published cone-be...
متن کاملNew , e cient Fourier - reconstruction method for approximate imagereconstruction in spiral cone - beam CT at small cone
We present an approximate algorithm for image reconstruction in spiral cone-beam CT at small cone-angles. The rst step of the algorithm is a rebinning from fanbeam to parallel beam projections, that is performed independently for each detector row. The result of this rebinning procedure is a set of parallel views, where all rays are tilted against the z-axis by their cone angle and the rays wit...
متن کاملVolume Reconstruction of Cone-Beam Geometry
The purpose of this manuscript is to provide a tutorial overview on the subject of cone-beam geometry devices imaging. Toward this end, we have tried to strike a balance among purely algorithmic issues, topics (tomosynthesis imaging etc.) dealing with how to generate data for reconstruction in different domains, and artifacts inherent to different data collection strategies. This manuscript is ...
متن کاملA Reconstruction Approach for Imaging in 3D Cone Beam Vector Field Tomography
3D cone beam vector field tomography (VFT) aims for reconstructing and visualizing the velocity field of a moving fluid by measuring line integrals of projections of the vector field. The data are obtained by ultrasound measurements along a scanning curve which surrounds the object. From a mathematical point of view, we have to deal with the inversion of the vectorial cone beam transform. Since...
متن کاملAn Approximate Cone Beam Reconstruction Algorithm for Gantry-Tilted CT Using Tangential Filtering
FDK algorithm is a well-known 3D (three-dimensional) approximate algorithm for CT (computed tomography) image reconstruction and is also known to suffer from considerable artifacts when the scanning cone angle is large. Recently, it has been improved by performing the ramp filtering along the tangential direction of the X-ray source helix for dealing with the large cone angle problem. In this p...
