后装治疗床在临床中的应用

Comparative analysis of clinical application of afterloading treatment table

目的:评估新旧后装治疗床在临床应用中的优劣。方法:通过分组对比的方法,比较新旧后装治疗床在使用中的灵活性及体外融合放疗时体位图像的匹配精准度。结果:旧型后装治疗床体位重复性欠佳,且在体外融合放疗图像匹配方面,Y方向上有统计学意义上的误差(P<0.05);新型后装治疗床体位重复性好,且在体外融合放疗图像匹配方面,X、Y、Z 3个方向上误差均没有统计学意义(P>0.05)。结论:新型后装治疗床与旧后装治疗床相比,更能够满足后装治疗的体位要求,提高了肿瘤治疗的效果,带来了技术上的革新。

Objective To evaluate the advantages and disadvantages of the new and old afterloading tables in clinical application.Methods Grouping comparison was used to make clear the flexibilities of the new and old afterloading tables in application as well as the position precision of image matching during in vitro fusion radiotherapy.Results The old table behaved not so well in position repeatability,and had significant errors at Y direction（P0.05） in image matching during in vitro fusion radiotherapy.The new table gained advantage in position repeatability,and had no significant errors at X,Y and Z directions（P0.05） in image matching during in vitro fusion radiotherapy.Conclusion The new treatment table is better for afterloading therapy than the old one,and enhances tumor therapy.
