CT image reconstruction via industrial CT fast scanning
Journal of InstrumentationAbstract In automated manufacturing and safety inspection, there is a high demand for fast computed tomography (CT) scanning and image reconstruction. Currently, faster scanning can be achieved by reducing the X-ray exposure time within sparse view CT. The faster scanning strategy introduces significant streak artefacts and noise

Parametric boundary reconstruction algorithm for industrial CT metrology application
Journal of X-Ray Science and Technology, 2009High-energy X-ray computed tomography (CT) systems have been recently used to produce high-resolution images in various nondestructive testing and evaluation (NDT/NDE) applications. The accuracy of the dimensional information extracted from CT images is rapidly approaching the accuracy achieved with a coordinate measuring machine (CMM), the ...

High-speed CT imaging for today's industry
Insight - Non-Destructive Testing and Condition Monitoring, 2008Computed Tomography (CT) has been extensively used in industrial inspection, however, production applications have been few, due to the time required for performing CT. This paper describes a high-throughput, production X-ray CT system for inspecting munitions. Various types of defects such as cracks, voids, fuse armed status, and powder fill level are

The System of Signal Acquisition and Processing of Industrial CT
2011 International Conference on Control, Automation and Systems Engineering (CASE), 2011The system of signal acquisition and processing in industrial CT can transfer analog signals outputted by X-ray linear array detector into digital signals and transmit them into computer after uniformity in order to supply data for the image reconstruction of measured object, which plays an important part in CT.

Perspective on the First 10 Years of the CT Scanner Industry
Academic Radiology, 2003In the spirit of full disclosure, it should be noted that the author of this article was in charge of GE Medical Systems from 1974 to 1986. During that time, he had no direct contact with GE competitors in the manufacture of computed tomographic (CT) scanners. Twenty years after the introduction of the CT scanner, however, during his retirement, he was

The influence of BRDF calibration to CT industry NDT
SPIE Proceedings, 2010Computed Tomography (CT) testing is an important non-destructive testing technology in industry inspection. So the important work of CT development is the value calibration and the precise result judgment. Bi-directional reflection distribution function(BRDF) as the common spatial characteristic parameter can be fit for the CT data structure in ...

Industrial Computed Tomography Technique Development for Industrial Volumetric X-Ray CT
Materials Evaluation, 2022It is often stated that no two engineers will set up an industrial X-ray computed tomography (CT) scan with the same parameters. In this article, an orderly set of steps is presented that will lead to an acceptable CT scan result for typical cone beam (volumetric) systems with application to denser and/or larger objects.

Experimental research on rear collimator in γ-ray industrial CT
Applied Radiation and Isotopes, 2009Rear collimator is one of the key components in the gamma-ray industrial CT, which plays an important role in removing scattering influence and improving the CT spatial resolution. High-performance CT is always associated with a high-quality collimator.

Interactive Volume Exploration for Feature Detection and Quantification in Industrial CT Data
IEEE Transactions on Visualization and Computer Graphics, 2008This paper presents a novel method for interactive exploration of industrial CT volumes such as cast metal parts, with the goal of interactively detecting, classifying, and quantifying features using a visualization-driven approach. The standard approach for defect detection builds on region growing, which requires manually tuning parameters such as ...
