摘　　要：目的保证全景X射线牙片机正常工作,并确保其辐射安全性。方法采用比拉那型X射线剂量计对4种全景牙片机辐射输出的空气比释动能率、重复性以及质量进行检测。结果此次检定的全景X射线牙片机基本可较好地达到JJG744-2004《医用诊断X射线辐射源检定规程》的指标要求。结论辐射检定是全景牙片机医学检定的重要组成部分,为制定辐射检定规范提供了参考。Objective To ensure the normal work and radiation safety of dental panoramic X-ray machine. Methods Air kerma rate, repeatability and quality of radiation output of four kinds of dental panoramic X-ray machines were detected with Piranha X-ray dosimeter.Resulta All the indicators of the four kinds of machines can meet the requirements of JJG744-2004 verification regulation of medical diagnostic X-ray radiation source.Conclusion As an important part of medical veriifcation of dental panoramic X-ray machine, radiation veriifcation can provide reference information for the formulation of radiation veriifcation standard.
