iMARIterative metal artifact reduction

The iterative algorithm for metal artifact reduction iMAR allows respective artifacts – caused by implants, artificial joints or pacemakers – to be reduced significantly. Such artifacts may lead in the worst case to non-diagnostic images by concealing the relevant pathologies.

Features & Benefits

iMAR reduces metal artifacts in various body regions. iMAR is designed to yield images with a reduced level of metal artifacts compared to conventional reconstruction if the underlying CT data is distorted by metal being present in the scanned object. 


  • Reduction of metal artifacts without increasing the radiation dose
  • Improve your process efficiency with an algorithm that can handle different metal implants in a smooth workflow
  • Leverage your ability to address more challenging cases (e.g. dental fillings, pacemakers, and extremity implants) and extend your referral base by delivering outstanding image quality
