The Application of Beam Hardening Correction for Industrial X-ray Computed Tomography
نویسندگان
چکیده
X-ray computed tomography (CT) is a non-destructive, radiographic scanning technique that enables the visualisation of both the internal geometry and the composition of a workpiece; X-ray CT is therefore well suited for non-destructive inspection tasks. Several physical processes reduce the quality of CT images, and therefore influence both qualitative and quantitative analyses made from CT data-sets; one such physical process is beam hardening. In this work a simulation-based method is presented for correcting beam hardening, this method is applied to industrial X-ray CT measurement tasks and demonstrated to improve CT image quality.

A Framework for Performance Assessment of Beam Hardening Correction Algorithms in Industrial Computed Tomography
Industrial computed tomography (CT) images often suffer from beam hardening (BH) artefacts. Since beam hardening correction (BHC) is crucial in industrial CT, it is worth acquiring a good understanding of the BHC algorithms. The purpose of this work concerns the development of a phantom-based framework to assess the performance of BHC algorithms in industrial CT, and its application on several ...
متن کاملArtifact reduction techniques in Cone Beam Computed Tomography (CBCT) imaging modality
Introduction: Cone beam computed tomography (CBCT) was introduced and became more common based on its low cost, fast image procedure rate and low radiation dose compared to CT. This imaging modality improved diagnostic and treatment-planning procedures by providing three-dimensional information with greatly reduced level of radiation dose compared to 2D dental imaging modalitie...

Objective: In this study, we aimed to validate the accuracy of computed tomography-based attenuation correction (CTAC) using the bilinear scaling method.Methods: The measured attenuation coefficient (μm) was compared to a theoretical attenuation coefficient (μt ) using four different CT scanners and an RMI 467 phantom. The effective energy of the CT beam X-rays was calculated, using the aluminu...
متن کاملBeam Hardening Correction in X-Ray Computed Tomography: A Comparison of Two Iterative Model-Based Reconstruction Methods
While the expenses for computational power decrease, iterative reconstruction methods for x-ray computed tomography (CT) that allow the use of improved model assumptions, become more attractive. In applications for non-destructive testing one of the most common degradations of image quality with standard x-ray CT reconstruction methods is beam hardening. Techniques for beam hardening correction...
متن کاملRefinement of Imaging Processing of Scatter Correction and Beam Hardening Tools for Industrial Radiography and Cone Beam CT
Digital detector arrays are used for industrial radiography and cone beam CT. Scattering and beam hardening artifacts reduce the achievable contrast sensitivity and can severely limit the size of the part to be scanned or require large amounts of shielding to block scatter outside the inspection area of interest. Varian’s image processing toolkit contains a set of dll’s that can easily be deplo...
