Practice and Study on Automatic Measurement of CT Spatial Resolution

    摘要
  • 摘要: 目的 利用MTF方法实现CT空间分辨率的自动测量。 方法 阐述了自动测量原理,采用Catphan体模和自制体模对CT空间分辨力进行了测量。 结果 主观法和客观法测试结果相近。 结论 可以用自制体模对CT的空间分辨率进行自动测量。

     

    Abstract: Objective To measure spatial resolution with MTF method. Method The Catphan phantom and self-prepared experimental phantom were used to measure spatial resolution based on the analyzing of measurement principle. Result the results of subject method was basically consistent with that of the object method. Conclusion it is feasible to do the automatic measurement for CT using self-prepared experimental phantom.
