| Summary: | X-Ray Computational Tomography (XCT) is a form of non-destructive testing used to
visualise components’ internal features and generate 2D images or 3D models of these
components. XCT is an essential tool in the industry for failure analysis and quality
control. The quality of scans can be significantly improved by modifying and adjusting
the X-Ray source characteristics and the detector receiving the X-Ray beams.
However, doing so can be very costly and complex due to the different tradeoffs when
adjusting these characteristics. Improving the proximity of the sample to the source
and ensuring sample straightness can also improve the quality of the scanned image.
As such, the fixture holding the sample plays a crucial role in obtaining a higher
resolution scanned image.
This report provides an overview on the design process of the new fixture and how it
improves on the drawbacks on current fixtures. Experimental investigations were
conducted to investigate the effectiveness of the new fixture on the scanning process
in terms of resolution of the image and the straightness of the sample. |
