Type: Quick start guide

GE blade|line is a precise and fast 450 kV X-ray CT inspection and measurement system for complex and critical high pressure turbine blades.

The system combines 2D and 3D inspection needs into one system. The extremely fast GE Jupiter linear detector array quickly generates radiographic 2D images that allow for easy and fast identification of critical internal structures in specific areas of interest for further verification by CT.

The CT slice measurement mode allows more detailed evaluations (wall thickness measurements and defect analysis) of internal casting components.

to reconstruct the tomographic slice image.

By vertically shifting the sample through the fan beam, the

required number of CT slices is compiled and analyzed at the

When compared with conventional cone beam CT, highly collimated fan beam CT oers improved resolution, as well as, a higher

quality CT slice result, due to the reduction of image artifacts caused by scattered radiation.

The Power of Rhythm / DICONDE

All the 2D and CT slice images acquired by the blade|line system

are automatically created in the non-proprietary and reliable

DICONDE(DigitalImagingandCommunicationinNDE)format.

DICONDE incorporates many features that are NDE-focused

describing all of the necessary syntax, attributes and data

elements. Users can evaluate, archive, transmit and receive

acquired data. The GE blade|line CT system uses the

well-establishedGERhythmSoftwareplatformforimage

analysis and data management.
