GE Introduces First Compact 300 kV CT System with < 1 ?m Detail Detectability

Wunstorf, Germany – 8 September 2011. The new phoenix v|tome|x m from GE’s Inspection Technologies business is the industry’s first compact 300 kV Computed Tomography system for 3D metrology and failure analysis with less than 1µm detail detectability.

The system offers excellent magnification and resolution for high absorbing metal samples. With up to 500 W it comes with also enough tube power to examine a broad range of parts, including light metal castings in just a few minutes. Its optional dual tube configuration allows high resolution nanoCT® of low absorbing samples. This versatility ensures the new system a wide spectrum of applications in materials science, industrial failure analysis, process control and 3D metrology in industrial sectors ranging from castings and electronics to plastics, geology and aerospace, including turbine blade inspection.

As Oliver Brunke, CT product manager for GE’s phoenix radiography product line, explains, “This new CT system extends our v|tome|x series and our unique 300kV/500W microfocus x-ray tube is now available for the first time in a compact lab system, complementing our large v|tome|x L walk-in version and our compact v|tome|x s. The phoenix v|tome|x m’s superior image quality is a result of its use of in-house technology for all hardware and software core components, including GE’s high-resolution X-ray tube technology and temperature-stabilized digital DXR X-ray detector arrays.

GE’s new CT system is suitable for 500 x 600 mm samples with a field of view up to 300 mm diameter and 600 mm in height and up to 50 kg in weight. It features granite-based manipulation and a temperature-controlled cabinet for extremely high measurement accuracy and repeatability and it is equipped with phoenix datos|x 2.0 CT software which allows fully automated data acquisition, volume processing and display, using the software’s click & measure|CT functionality. 3D reconstruction results are available within minutes with the system’s velo|CT.

The system’s high magnification derives from GE’s design of its 300kV microfocus unipolar tube, whose minimum working distance from the focal spot to the X-ray beam exit window is just about 4.5 mm. This contrasts with conventional, bipolar tubes which have longer minimum working distances, increasing the focal spot to target object distance and hence limiting magnification. For particularly high resolution scans, an optional 180 kV high power nanofocus tube can be selected at the touch of a button.
