Novel Detection Techniques for Ion Beams - E0406

previously: "2-dimensional detectors for ion beam radiotherapy" within the Heavy Ion Therapy Project at DKFZ.

• Specialisation on development of new measurement methods for:
  • ion spectroscopy: investigation of nuclear interactions of ion beams with the patient
  • ion radiography: high resolution imaging with ion beams
  • monitoring of therapy delivery: visualisation of the ion beam in the patient
  • development of quality assurance measurements for ion beams including verifications of patient treatment plans

• Transfer of the new methods into clinical application at the Heidelberg Ion Beam Therapy Facility
