By incorporating much of the technology which has been proven by GE in the healthcare sector over four decades, the new CT system is up to 200 times faster than conventional 3D CT inspection and offers important additional quality control features, including exact 3D defect location and classification, wall thickness analysis to allow dimensional control and actual - CAD data comparison.
Fast atlineCT with GE’s new speed|scan CT System allows up to 100% 3D inspection of castings and composite samples
The scanned samples are automatically analysed with GE’s newly developed high-speed 3D evaluation algorithms
GE’s speed|scan atlineCT is suitable for any production line where there is a constant requirement for stringent quality control of light metal castings or composite structures but is particularly targeted at the automotive and aerospace sectors.
“The new inspection system can reduce typical scan times for an engine cylinder head from several hours with conventional fan beam CT to less than two minutes,” says Oliver Brunke, Lead CT Product Manager for the Inspection Technologies business, “This means that all of the benefits of 3D compared with 2D inspection can now be realized at the production line. These include benefits such as reduction in reject rate by analyzing position and form of defects which may be machined out by subsequent processes to prevent unnecessary failure sentencing and by accurately checking work piece geometry and dimensions, so that form and size deviations can be easily identified and corrected at an early stage of the production process. Finally, depending on their size and absorption behaviour even foreign materials like inclusions or sand core remains may be detected, located and classified according to its density and position.”
The modified GE medical scanner in speed|scan atlineCT system uses Helix multi-line technology, where a gantry with an X-ray tube and corresponding multi-line X-ray detector rotates around the work piece, which is being passed through the gantry on a conveyor belt. The work pieces are scanned at speeds of up to several millimeters per second, and are automatically assessed with the aid of GE’s own speed-optimized 3D Automatic Defect Recognition (ADR) algorithms. Inspection is carried out using a new workflow concept, where the work piece is loaded onto the conveyor belt of the system which is located adjacent to the production line. The continuous CT scan takes place and the software begins volume reconstruction and optimization. The work piece is unloaded and a new work piece placed on the belt for scanning. At the same time, 3D ADR is taking place on the first work piece volume to allow rapid sentencing. The second and subsequent work pieces then follow the same procedure.
The new speed|scan atlineCT inspection system can handle work pieces up 300x400x800mm in size and up to 50kg in weight and its robust design allows 24/7 operation. Its containing cabinet is suitable for industrial environments with dust protection and thermal isolation and the radiation safety cabinet offers full protective installation according to the German RÖV standard and the US 21 CFR 1020.40 standard.http://ge-mcs.com/speedscan

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
