摘要
目的：验证ＨＹ－ＨＤＲ１８型遥控后装治疗机所用施用器周围的剂量分布。方法：用ＴＬＤ（热释光剂量计）［ＬｉＦ（ＭＧ，Ｃｕ，Ｐ）］测量并验证由ＨＹ－ＨＤＲ１８型后装治疗计划系统设计的针对宫颈癌的妇科治疗计划及施用器周围的剂量分布。结果：ＴＬＤ测量值与ＴＰＳ计算值偏差４．２±２．５％。结论：理论值与实测值接近。
Objective: To verify the dose distribution around the gynecology applicators determined by the Treatment Planning System (TPS) of HY HDR 18. Methods: The dose distribution around the gynecology applicators was measured by LiF(Mg,Cu,P) chips (TLD). Results: The variations between TLD measurement and calculation of gynecology treatment plan are 4.2±2.5%. Conclusion: In the gynecology treatment plan formed by TPS(of HY HDR 18), the calculation data conform to that of experiment.HY HDR is very suitable for clinical use.
