西门子AR系列CT机的环状伪影分析

The Analysis of Ring Artifacts SOMATOM AR

    摘要
  • 摘要: 本文分析了西门子AR系列CT机的环状伪影的产生原因,除了环境温度湿度变化会引起环状伪影外,如气体探测器(Detector)通道板(Hybrid)以及A/D数据转换板(DAB)等器件的老化和故障是产生环状伪影的主要原因。并且环状伪影的产生还与DAS与球管,准直器(Collimator)之间的相对位置及角度有关。

     

    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.
