Analysis of the effect of cone-beam geometry and test object configuration on the measurement accuracy of a computed tomography scanner used for dimensional measurement

This paper uses a test object to quantify geometrical errors contained within a cone-beam X-Ray source and describes a model for defining parameters influencing dimensional accuracy and repeatability of images produced. This work helps overcome factors restricting the expansion of MicroCT as a metrology tool within a wide range of industrial applications. Outputs from this research include a £498K multi-disciplinary EPSRC research project (EP/K031066/1) developing novel statistical methods for assessment of ALM structures and an £80K EngD sponsored by BAE Systems (mark.wilson2@baesystems.com). The output has also been applied by 4 international research groups establishing MicroCT as a reliable measurement technique.
