Available in PDF, EPUB and Kindle. Book excerpt: The application of X-ray computed tomography (CT) for aircraft and aerospace structure and ancillary equipment has been investigated in the Advanced Development of X-Ray Computed Tomography Applications demonstration (CTAD) program sponsored by the NDE Branch of the Materials Directorate at the Air Force Wright Laboratory (WL). X-ray CT offers a new inspection capability for aircraft hardware that provides quantitative information on material density/constituents and dimensions. This capability has economic value as an engineering tool for improving the evaluation and control of materials and processes used in aircraft/aerospace structures. The CTAD effort has investigated a wide variety of application areas for CT. These include electronics, closed systems, castings, composites, and advanced materials and processes. Applications of CT in these areas include: configuration control, anomaly detection, dimensional measurements and material uniformity. By using the actual dimensional characteristics of features and anomalies in a component, and the material characteristics, such as density and elemental composition, that are derivable from the CT data, engineers can perform a variety of analyses to arrive at quantitative measurements that are of economical value to improving the overall product cycle from development to deployment. Until specifications requiring CT are implemented, CT will be employed primarily as a supplement to other NDE methodologies for engineering evaluations such as product development/ material characterization measurements, failure analysis and engineering problem solving, noninvasive micrography and geometry acquisition.

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.

Download or read book Cone Beam Computed Tomography written by Chris C. Shaw and published by Taylor & Francis. This book was released on 2014-02-14 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional computed tomography (CT) techniques employ a narrow array of x-ray detectors and a fan-shaped x-ray beam to rotate around the patient to produce images of thin sections of the patient. Large sections of the body are covered by moving the patient into the rotating x-ray detector and x-ray source gantry. Cone beam CT is an alternative technique using a large area detector and cone-shaped x-ray beam to produce 3D images of a thick section of the body with one full angle (360 degree or 180 degree plus detector coverage) rotation. It finds applications in situations where bulky, conventional CT systems would interfere with clinical procedures or cannot be integrated with the primary treatments or imaging systems. Cone Beam Computed Tomography explores the past, present, and future state of medical x-ray imaging while explaining how cone beam CT, with its superior spatial resolution and compact configuration, is used in clinical applications and animal research. The book: Supplies a detailed introduction to cone beam CT, covering basic principles and applications as well as advanced techniques Explores state-of-the-art research and future developments while examining the fundamental limitations of the technology Addresses issues related to implementation and system characteristics, including image quality, artifacts, radiation dose, and perception Reviews the historical development of medical x-ray imaging, from conventional CT techniques to volumetric 3D imaging Discusses the major components of cone beam CT: image acquisition, reconstruction, processing, and display A reference work for scientists, engineers, students, and imaging professionals, Cone Beam Computed Tomography provides a solid understanding of the theory and implementation of this revolutionary technology.
