目的通过对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,不同部位受照体表剂量进行统计分析。结果平均体表剂量中肝癌患者腹正中最高,为(125.50±215.49)mGy,其次为肿瘤患者。个体受照剂量最高为1 097.00mGy,为骶尾部脊索瘤患者。上球管较下球管使患者受照剂量高。结论介入操作中,患者受照剂量差别很大,受多种因素影响:病种、手术复杂程度、术者的操作技术等。因此,应采取有效防护措施使患者的受照剂量合理降低,特别是主动防护。
Objective To explore the main factors influencing radiation dose by analyzing the radiation dose of different patients during the interventional therapy. Methods The application of thermoluminescence measurement method for different diseases, different parts of the body surface dose statistics were analyzed. Results The mean body surface dose of liver cancer patients was the highest in the belly median (125.50 ± 215.49) mGy, followed by tumor patients. Individual exposure dose up to 1 097.00mGy, for the sacrococcygeal chordoma patients. On the lower tube of the tube so that patients under high doses of radiation. Conclusion In the interventional operation, the dose of patients varies greatly, and is affected by many factors: the type of disease, the complexity of the operation, the operation technique of the surgeon and so on. Therefore, we should take effective protective measures to reduce the patient’s dose reasonable, especially active protection.
