摘　　要：作者就ｘ射线机准直系统的测试及校准方法作了探讨，提出新的测试及校准方法，并附有１０台Ｘ射线机准直系统的测试报告和３台Ｘ射线机准直系统的校准后的结果报告，通过此方法可使Ｘ射线机的光野与照射野一致性的精度进一步提高，可为Ｘ射线照片质量控制提供参考。A new testing and calibration method for X-ray collimation system was proposed by the authors:The resuIts of testing in 10 X-ray units and after calibration in 3 units were reported。The precision that light filed and radiation field were in accordance with each other was improved by calibration and correction using this new approach whichwill also be helpful to radiographic quality control.
