Summary
Contractor: Quentin Adam –Adam Mechanica Pty Ltd
Summary: The goal of this project's third stage was to determine a feasible scanner/gantry configuration for an electron beam tomography (EBT) x-ray scanner that could be used to create three-dimensional images of the interior of carcases. This objective carcase measurement (OCM) data would be used for robotic control of carcase cutting and analysing carcases for meat quality in abattoirs.
At the heart of the EBT concept is an unusual linear anode featuring multiple electron beam targets acting as a linear array of x-ray sources that has the potential to reduce scan time to collect OCM data.
This particular project component is the last of three, dealing with technical issues in applying EBT as a method of industrial scale CT. This report describes feasible configurations of the EBT gantry and applicable reconstruction algorithms. The important conclusive points are;There are three simple feasible configurations of the gantry, one rotational where the scanner revolves around the carcase, and two translational gantries, where the scanner moves vertically up and down past the carcase.A rotating scanner has the least technical risk for image reconstruction.There will be a trade-off between the choice of scanner configuration, hardware cost and reconstructed image quality that is not quantified to date.Developing a completely static scanner, without any moving gantry or parts, would likely be too technically risky and expensive.
