摘要
目的:评价立体定向放射治疗设备的安全性检测,保障立体定向放射治疗设备的安全使用。方法:根据国家相关标准制定立体定向放射治疗设备安全性检测步骤和评价方法,分析评价5种不同品牌的立体定向放射治疗设备的机械精度、输出剂量和射野输出均匀性等指标。结果:经对5种立体定向放射治疗设备检测,其等中心精度、光射野一致性、射野输出均匀性以及机架角度改变情况下的X射线输出剂量存在明显差异;而治疗床、治疗头及机架机械精度、输出剂量以及不同剂量率下X射线输出剂量差异不明显。结论:制定立体定向放射治疗设备安全性检测评价方案,对立体定向放射治疗设备进行安全性检测,可为立体定向放射治疗设备的安全性能提供保障。
Objective: To evaluate the safety detection of stereotactic radiotherapy equipment and ensure the safe application of this kind of equipment. Methods: According to the relevant national standards to formulate the procedure and evaluation method of safety detection of stereotactic radiotherapy equipment, as well as to analyze and evaluate series indexes included mechanical accuracy, output dose and uniformity of field output of stereotactic radiotherapy equipments of 5 kinds of brands. Results: Through detected the five kinds of stereotactic radiotherapy equipments, there were obvious differences in isocentric accuracy, consistency of optical field, uniformity of field output, and the output dose of X-ray when the frame angle was changed. While, there were no significant difference in mechanical accuracy and output dose of treatment bed, treatment head and rack, as well as output dose of X-ray under different dosage rate. Conclusion: The formulation of evaluation scheme of safety detection of stereotactic radiotherapy equipment can implement safety detection for this kind of equipment and can provide guarantee for safe performance of this kind of equipment.
