Abstract: There is described a method and apparatus for collecting Tomographic inspection data of objects using Compton scatter radiation. The apparatus is of size and weight for portable use within industrial facilities and may be used for assessing integrity of infrastructures in terms of material density, missing materials, thickness of materials, and identification of foreign materials.

Abstract: The method is for inspecting an infrastructure having a corrugated pipe at least partially surrounded by soil. The corrugated pipe has a cylindrical wall which is corrugated along a length thereof and forming a longitudinally extending series of corrugations. The method generally has the steps of emitting, outwardly from the interior of the corrugated pipe, a beam of radiation particles directed towards a given voxel positioned beyond an inner face of the cylindrical wall and along a scanning plane parallel to an orientation of individual ones of the corrugations of the cylindrical wall; detecting backscattered photons scattered back from the given voxel and along the scanning plane; and generating inspection data based on the detected backscattered photons associated with the given voxel for use in inspecting the corrugated pipe.
