Participation in “Cells in Motion”

  • Project FF-2017-19 – Characterization of the particle drift behavior of a novel PET detector concept using heavy dielectric organometallic liquids (Klaus Schäfers, Christian Weinheimer; project time: 11/2017 - 12/2018)
  • Project FF-2013-16: PET imaging of freely moving mice (Xiaoyi Jiang, Frank Wübbeling, Klaus Schäfers, project time: 07/2013 - 06/2016)

“I became a scientist by chance“ – an interview

For Prof Klaus Schäfers everything revolves around motion correction. He and his team aim to make clinical images even more exact. And they have no lack of ideas for improving high-tech equipment.
