Artifact 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...
متن کاملThe Application of Beam Hardening Correction for Industrial X-ray Computed Tomography
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 dat...
متن کاملValidation of computed tomography-based attenuation correction of deviation between theoretical and actual values for four computed tomography scanners
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 کاملA 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 کاملMulti-Material Beam Hardening Correction(MMBHC) in Computed Tomography
In computed tomography (CT), the nonlinear attenuation characteristics of polychromatic X-rays cause beam hardening artifacts in the reconstructed images. State-of-theart methods to correct the beam hardening effect are mostly single material precorrections (e.g. water-precorrection), which are far less efficient when more than one material is present in the field of measurement. The use of tho...
