SimCT is an in-house software tool and is only provided to development partners.

Tools that perform numerical simulations of X-ray imaging like SimCT help users of X-ray imaging devices to get a better understanding for consequences of physical effects that are relevant for their application. Engineers and developers of X-ray devices use numerical simulations as essential tool during the design and prototyping phase of new imaging systems and software developer can use virtually acquired data for testing reconstruction algorithms, artefact correction methods as wells as any kind of image processing to improve or evaluate X-ray images. Besides that, SimCT provides procedures to optimise the image quality by automatically determining suitable scan parameters for a user-defined scan task to minimise influences of noise, image blur as well as artefacts. Summary of application areas:

  • Gain knowledge about XCT
    • attenuation, scattering and any kind of artefacts
    • geometrical effects
  • Optimization of scan parameter
  • Correction of real scans
  • Simulation help to design new XCT devices
  • Generate virtual XCT data with known properties to develop and evaluate
    • image processing algorithms
    • reconstruction algorithms
  • Estimation of measurement uncertainty
