Book Synopsis Industrial X-Ray Computed Tomography by : Simone Carmignato
Download or read book Industrial X-Ray Computed Tomography written by Simone Carmignato and published by Springer. This book was released on 2017-10-18 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray computed tomography has been used for several decades as a tool for measuring the three-dimensional geometry of the internal organs in medicine. However, in recent years, we have seen a move in manufacturing industries for the use of X-ray computed tomography; first to give qualitative information about the internal geometry and defects in a component, and more recently, as a fully-quantitative technique for dimensional and materials analysis. This trend is primarily due to the ability of X-ray computed tomography to give a high-density and multi-scale representation of both the external and internal geometry of a component, in a non-destructive, non-contact and relatively fast way. But, due to the complexity of X-ray computed tomography, there are remaining metrological issues to solve and the specification standards are still under development. This book will act as a one-stop-shop resource for students and users of X-ray computed tomography in both academia and industry. It presents the fundamental principles of the technique, detailed descriptions of the various components (hardware and software), current developments in calibration and performance verification and a wealth of example applications. The book will also highlight where there is still work to do, in the perspective that X-ray computed tomography will be an essential part of Industry 4.0.

Book Synopsis Handbook of Advanced Nondestructive Evaluation by : Nathan Ida
Download or read book Handbook of Advanced Nondestructive Evaluation written by Nathan Ida and published by Springer. This book was released on 2019-07-29 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook is a comprehensive source of information on all aspects of non-destructive testing (NDT), for use by professionals, educators, and most of all, by the practitioners of testing. The art of NDT consists of dozens of methods, some classical, and some emerging. As the pace of industrial work and discovery intensifies and materials are utilized to their physical limits, the role of NDT becomes ever more important. As a result, the methods of testing are themselves evolving, and it is the intent of this book to capture this evolution. Handbook of Modern Non-Destructive Testing broadens the scope from traditional books on the subject. In addition to classical, emerging and exotic methods of evaluation, the book will also cover the use of NDT techniques in other fields, such as archaeology or resource exploration. With contributions from experts in all areas of the field, the reader will find balanced coverage of a variety of testing methods, with no bias against or endorsements of any particular method. The book treats many areas in depth, covering all aspects of testing, and will include case studies where appropriate. Additional coverage of statistical methods and their use, as well as simulations‘ role in testing and test design, are included.

Book Synopsis Scatter Correction for Spectral Computed Tomography by : Odran Pivot
Download or read book Scatter Correction for Spectral Computed Tomography written by Odran Pivot and published by . This book was released on 2019 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scattered radiation is a major cause of bias, loss of contrast and artifacts in x-ray computed tomography (CT). Many correction methods have been proposed for conventional CT (using energy-integrating detectors) but it is still an open research topic in the field of spectral CT, a novel imaging technique based on the use of energy-selective photon counting detectors. The main objective of the present thesis was to investigate scatter correction techniques adapted to spectral CT. The chosen solution refines a scatter correction method developed for integration-mode CT which uses a semi-transparent primary modulator mask. The attenuation of the primary modulator mask is first compensated for with a correction matrix which takes advantage of the spectral information. The other contributions are a scatter model based on B-splines allowing an accurate representation of scatter maps with the aid of a very few parameters and a cost function which takes into account the structures of the mask and the object. The accuracy of the correction matrix, the scatter model and the whole proposed scatter correction process were tested on simulated data considering photon counting detectors with various numbers of energy bins and have shown a significant bias reduction, contrast enhancement and artifact removal. In addition, physical experiments were performed using a parallel fan-beam set-up with a commercial energy-resolved detector. The method was successfully validated in the case of two phantoms dedicated to medical image quality measurements, with a remarkable improvement.

Book excerpt: X-ray computed tomography (CT) is a technique that allows non-destructive imaging and quantification of internal features of objects. X-ray CT reveals differences in density and atomic composition and can therefore be used for the study of porosity, the relative distribution of contrasting solid phases and the penetration of injected solutions. In this book, various applications of X-ray CT in the geosciences are illustrated by papers covering a wide range of disciplines, including petrology, soil science, petroleum geology, geomechanics and sedimentology.
Book Synopsis X-Ray Computed Tomography for Failure Analysis Investigations by :
Download or read book X-Ray Computed Tomography for Failure Analysis Investigations written by and published by . This book was released on 1993 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Failure analysis is an important engineering evaluation in any product development cycle; essential to product reliability and evolution. The volumetric feature detection and three-dimensional positioning capability of X- ray computed tomography are valuable and cost saving assets to a failure analysis laboratory. Savings are realized in reduced risk, determination of proper direction for irreversible failure analysis activities and schedule improvement. Savings are realized in reduced risk, determining proper direction for irreversible failure analysis activities and schedule improvement. Failure analysis laboratories of sufficient size can justify the cost saving benefits of using CT for equipment procurement. Case studies of failure analyses have been demonstrated to the Air Force and industry showing the ability of CT to significantly benefit such studies. In some cases, CT can directly resolve the problem, and in other cases, provides key supplemental information for guiding further investigations and reducing the risk of incorrect or incomplete analysis. Examples have included mechanical and electrical system assembly, system internal measurements and fitups, and material damage evaluation. CT also can be applied to systems to observe the internal positions as a function of test conditions. High resolution (>4 lp/mm) CT with combined radioscopy (real- time radiography) capability is advocated for failure analysis facilities ...

Book Synopsis Optimizing X-Ray Computed Tomography Settings for Dimensional Metrology Using 2D Image Analysis by : Younes Chahid
Download or read book Optimizing X-Ray Computed Tomography Settings for Dimensional Metrology Using 2D Image Analysis written by Younes Chahid and published by . This book was released on 2020 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current way to choose X-ray computed tomography (XCT) scanning settings is usually manual and prone to operator errors. This paper presents an effective semiautomatic protocol that proves a high correlation between the local contrast-to-noise (CNR) of XCT two-dimensional (2D) projection image (prior to reconstruction) quality and the resulting XCT 3D volume scan quality. This high correlation allowed the comparison of four XCT settings to determine the one with the smallest error, solely by locally using the CNR equation on one 2D projection (prior to reconstruction) of an additive manufactured lattice structure. Verification of the protocol was done by using a workpiece and comparing the chosen XCT setting reconstructed workpiece dimensions to the ones measured using a coordinate-measuring machine (CMM). This new method can reduce the operator error and time needed to compare different XCT setting combinations. The proposed protocol is a step closer to an automated XCT parameter selection procedure, limiting user dependency and error while increasing accuracy and fidelity.
