    • Abstract
  • The reason why ring artifacts appear in Somatom AR is analysed. The appearance of ring artifacts is related with working temperature and humidity. The hardware (includes Detector, hybrid and A/D inverter) multifunction is the main causes. The ring artifacts is also caused by position and angle's dis-adjustment between DAS, Tube and Collimator.
