Investigate the spectral interaction of X-ray and learn how to take advantage of this for production applications.

Background

FOSS analytics uses x-rays to monitor the weight and the fat content in meat at a rate of 38 tons/hour. Fat and meat have almost the same response to x-rays and variations in the thickness of the samples can have an important influence on the accuracy of the analysis. FOSS uses dual energy detectors to evaluate the absorption signal for the sample in different energies ranges of the x-rays. When multiple signals are obtained of the same sample the discrimination gets better; however variation in the detector production influences the acquired signal and the detection algorithm.

Task

You will need to measure how meat and fat interacts with x-rays for different parts of the energy spectrum. You will compare the spectral sensitivity of different detectors and use knowledge of detector physics to develop models which make a simple parametrization of variations in the detector performance and sample conditions.  The combined knowledge will be used to present recommendation to optimize the meat/fat contrast and increase the robustness for variation in measure conditions.  The measurements will be performed in NEXMAP’s laboratories but with access to production units from FOSS.
