AbstractThe course offers an overview of the engineering principles of radiation-based imaging methods as X-ray/gamma and neutron imaging. Special attention is given to the application of such methods to nuclear engineering, industrial and civil safety problems. The Lecture is complemented with numerical and hands on laboratory exercises.
ObjectiveUnderstanding of the principles and applicability of radiation-based imaging methods as radiography and tomography, their mathematical principles and the necessary data and signal processing methods. The lecture gives an overview of the associated radiation source and imaging detector technologies.
ContentPrinciples of computed tomographic imaging (inverse problems, Radon transformation, central slice theorem); parallel, fan-, and cone-beam and limited angle tomography; image filtering and conditioning methods; back projection algorithms (FBP, ART, direct FFT, FDK); resolution and contrast; scatter and beam hardening artefacts; image rendering and segmentation; Radiation source technology: X-ray tubes/LINACs, synchrotrons, gamma sources, neutron sources (reactor, spallation, accelerator based, neutron generators); detector technology: interaction mechanisms for photons and neutrons, detector materials, resolution and efficiency; applicability and complementarity of photon vs. neutron based imaging techniques; thermal and fast neutron imaging; combined imaging modalities; Applications in nuclear technology: fuel bundle research (thermal-hydraulics, cladding hydration, spent fuel characterization etc.); non-nuclear industrial applications: multi-phase flows in oil and chemical industry, fuel cell research, cultural heritage investigations, PEPT etc.; applications in nuclear safe guards; applications for citizen and homeland security; More exotic approaches: energy selective imaging; TOF, ultra-fast X-ray tomography using deflected electron beams; the course is complemented with numerical exercises and hands on laboratory demonstrations (neutron imaging demo at ICON/PSI, X-ray/gamma imaging at ETH/PSI).
Lecture notesLecture slides, additional readings and exercise materials will be provided.
