目的提出在美国X线透视引导下操作病人辐射剂量的初步参考值。材料与方法这是对来自介入放射学操作辐射剂量(RAD-IR)研究数据所作的第二次分析,研究方案得到机构伦理委员会批准并符合HIPAA要求。计算RAD-IR研究中每种操作的剂量分布(百分位数),每一组数据至少含有30例病例。剂量分布的 Objective To propose a preliminary reference value for operating a patient’s radiation dose guided by X-ray in the United States. Materials and Methods Here is a second analysis of the data from the Interventional Radiological Operational Radiation Dose (RAD-IR) study, which was approved by the Institutional Ethics Committee and meets HIPAA requirements. The dose distribution (percentiles) for each procedure in the RAD-IR study was calculated and each set contained at least 30 cases. Dose distribution
