Calculation Model of X-Ray Computed Tomography with Density Assessment Function

Abstract

Abstract— A calculation model of X-ray computed tomography with a density assessment function in the geometry of a parallel beam has been proposed. The model includes blocks for simulating and correcting sinograms and reconstructing section images. When generating sinograms, the parameters of the test object, source, and recorder of X-ray radiation have been taken into account. Modeling algorithms are implemented in the MathCad system and tested on virtual test objects.

Algorithm of Estimation of the Degree of Porosity Homogeneity of Foamed Concretes by Local Volumes by X-ray Computed Tomography Method

“…Let the set S be a combination of all points of detection with (y,z) coordinates. The test specimen s shadow belongs to set S. The XCT formation of the projection system is based on the approach proposed in [19,29]. The X-ray intensity I with the maximum energy Emax is recorded by a scintillation detector of hsc thickness at the point (y,z) and is associated with the parameters of the test specimen turned around the axis of rotation to θ angle:…”
