In brief

  • Researchers from the ETH Zurich, the Paul Scherrer Institute PSI, the Cantonal Hospital Baden and the University Hospital Zurich have achieved a milestone on the way to improved breast cancer screening.
  • They have demonstrated that breast tumours can be detected earlier with a new type of 3-D X-​ray computed tomography than with conventional computed tomography.
  • The new grating interferometry computed tomography clearly surpasses the conventional method in terms of resolution and contrast. This will increase the chances of recovery for affected women.
