Two-step radon inversion processing for amp;phgr;-planes having local radon origins

摘要

A two-step 3D Radon inversion processor for processing Radon data on a set of vertically oriented co-axial &phgr;-planes that partition Radon space, wherein each of the &phgr;-planes is sampled during the processing so as to have its own independent local Radon origin. In accordance with further principles of the present invention, a 3D Radon data generator generates Radon data on a set of vertically oriented co- axial &phgr;- planes that partition Radon space, wherein each of the &phgr;- planes is sampled so as to have its own independent local Radon origin, and a two- step 3D Radon inversion processor independently processes each of the . phi.-planes. Any shift of the local Radon origins with respect to a global coordinate system is compensated for during the 3D Radon inversion processing. Compensation for the origin shift may be made during or after a first step of the Radon inversion processing.
