目的通过对不同年份介入治疗过程中不同患者所受辐射剂量的分析,探讨影响辐射剂量的主要因素。方法应用热释光测量法,对不同疾病患者体表受照剂量进行测量、统计分析。结果介入操作中,患者受照剂量差别很大,受多种因素(设备性能、病种、手术复杂程度、术者的操作技术等)影响。平均体表剂量中肝癌患者后背正中最高,为(142.92±75.56)mGy,其次为肿瘤患者。个体受照剂量最高为1 097.00 mGy,为骶尾部脊索瘤患者。2011年患者受照剂量较2009年呈不同程度的上升。结论应采取各种有效措施使患者的受照剂量合理降低,特别是主动防护。
Objective To analyze the radiation dose of different patients in different years of interventional therapy to explore the main factors affecting the radiation dose. Methods Using the method of thermoluminescence measurement, the body surface dose of different diseases were measured and statistically analyzed. Results Interventional operation, the patient doses vary widely, subject to a variety of factors (equipment performance, disease types, surgical complexity, the surgeon’s operating skills, etc.). Mean body surface dose of liver cancer patients with the highest median of the back, (142.92 ± 75.56) mGy, followed by cancer patients. Individual exposure dose up to 1 097.00 mGy, for patients with sacrococcygeal chordoma. In 2011, the doses of patients increased to some extent from 2009. Conclusion All kinds of effective measures should be taken to reasonably reduce the dose of patients, especially active protection.
