目的 简述改进型腹板在直肠癌术后放疗中的应用方法,并探讨其对摆位重复性的影响.方法 对改进型腹板的应用方法进行说明,运用锥形束CT对使用常规型腹板、改进型腹板放疗患者的分次内及分次间摆位误差分别进行测量,并对数据进行分析,得出结论.结果 运用常规型腹板患者分次内摆位误差在x轴差异无统计学意义(P＞0.05),在v、z轴差异均有统计学意义(均P＜0.05);分次间摆位误差在x轴差异无统计学意义(P＞0.05),在v、z轴上差异均有统计学意义(均P＜0.05).运用改进型腹板患者分次内摆位误差及分次间摆位误差在x、v、z轴上差异均无统计学意义(均P＞0.05).结论 运用改进型腹板固定对摆位误差重复性的控制方面比常规型腹板更具有优势,有利于提高患者治疗的准确性.
目的 簡述改進型腹闆在直腸癌術後放療中的應用方法,併探討其對襬位重複性的影響.方法 對改進型腹闆的應用方法進行說明,運用錐形束CT對使用常規型腹闆、改進型腹闆放療患者的分次內及分次間襬位誤差分彆進行測量,併對數據進行分析,得齣結論.結果 運用常規型腹闆患者分次內襬位誤差在x軸差異無統計學意義(P＞0.05),在v、z軸差異均有統計學意義(均P＜0.05);分次間襬位誤差在x軸差異無統計學意義(P＞0.05),在v、z軸上差異均有統計學意義(均P＜0.05).運用改進型腹闆患者分次內襬位誤差及分次間襬位誤差在x、v、z軸上差異均無統計學意義(均P＞0.05).結論 運用改進型腹闆固定對襬位誤差重複性的控製方麵比常規型腹闆更具有優勢,有利于提高患者治療的準確性.

Objective To evaluate the application of improved belly board in postoperative patients of rectal cancer radiotherapy and explore the influence of its set-up repeatability.Methods CBCT was used to measure the intra fractional and inter fractional setup errors using normal or improved belly board respectively.The data was analyzed with statistic method.Results There was no significance of intra fractional setup errors on x-axis (P ＞ 0.05).There was significance on y and z-axis (P ＜ 0.05).There was no significance of interfrational setup errors on x-axis (P ＞ 0.05) and there was significance on y and z-axis (P ＜ 0.05) using normal belly board.There was no significance of intrafractional setup errors on x,y and z-axis (P ＞ 0.05).There was also no significance of interfractional setup errors on x,y and z-axis (P ＞ 0.05) with using improved belly board.Conclusion The method of improved belly board has more advantage than nomal belly board in controlling set-up repeatability,and it is conductive to improve accuracy of patients treatment.
