including development of methods for CT scan with micrometer resolution in manufacturing, methods for achieving the extremely high computational rates as the basis of CT scan in food production and research on new sources and methods for signal conditioning as a basis for detailed analysis in biological tissue.”

Transcript of CT Scanning applications in Food and Agriculture

  • 1. The Hounsfield Facility3D X-ray imaging

2. Imaging plant roots in soil 3. But CTX-rays canprobe the rootstructure in soilCT3D qualitativeandquantitativeNon-invasive/non-destructiveHigh resolution(1m-5mm)No samplepreparation 4. The Hounsfield Facility 3 CT Scanners from 0.5 m to 5 mm resolution Accommodating samples up to 25 cm diameter & 1 m length Automated sampling system enabling 4-D visualisation Automated root imaging via RooTrak 5. Applications of X-ray CT to soil sciencesRevealing the complexity in The impact of soil managementstructureExploring the role of microbesAssessing the fate of contaminants 6. Soil contact influences root developmentMaize in structure-less soil Maize in structured soilIn collaboration with Jose Dinneny (Carnegie Institution for Science, Stanford) 7. High resolution scanning:visualisation of wheat root hairs 8.
