【摘要】：目的:评估头体一体式固定板在全中枢放射治疗(CSI)中的应用。方法:回顾性分析43例使用头体一体式固定板进行全中枢放射治疗的患者,在治疗过程中将扫描图像与数字重建放射影像(DRR)进行配准,其中包括头颈段、胸段和腰骶段3部位图像,自动配准调整患者在X轴、Y轴和Z轴方向的摆位误差,并采用SPSS 22.0软件进行数据分析。结果:头颈段、胸段和腰骶段X轴摆位误差分别为(0.122±0.120)cm、(0.074±0.211)cm和(0.083±0.096)cm;Y轴摆位误差分别为(0.202±0.154)cm、(0.236±0.175)cm和(0.283±0.187)cm;Z轴摆位误差为(0.136±0.127)cm、(0.249±0.472)cm和(0.272±0.211)cm,3个方向均小于临床设定误差范围(头0.3 cm,体0.5 cm),差异具有统计学意义,头颈段(t=-13.091,t=-5.598,t=-11.423;P0.05);胸段(t=-17.814,t=-13.325,t=-4.699;P0.05);腰骶段(t=-33.632,t=-8.974,t=-8.390;P0.05)。儿童与成人头颈段、胸段和腰骶段3部位的X轴、Y轴和Z轴3个方向比较均无差异,头颈段(t=0.698,t=1.028,t=1.691;P0.05);脊髓段(t=1.376,t=0.469,t=1.179;P0.05)。头颈段、胸段和腰骶段两两比较中,X轴方向无差异(F=2.035,P0.05),Y轴、Z轴方向差异有统计学意义(F=3.777,F=3.895;P0.05)。结论:在CSI中应用头体一体式固定板新方法对患者进行仰卧体位固定,其摆位误差小,操作方便,患者顺从度和舒适度明显提高,儿童及成人均可使用。
[Abstract]:Objective: to evaluate the application of head-body integrated plate in CSI. Methods: a retrospective analysis was made of 43 patients who underwent total central radiotherapy with head and body fixation plates. During the course of treatment, scanning images were registered with digital reconstruction radiography (DRR), including head and neck segments. Chest segment and lumbosacral segment images of 3 parts were automatically registered to adjust the position errors in X axis Y axis and Z axis. SPSS 22.0 software was used to analyze the data. Results: the axial pendulum errors of head and neck segment, thoracic segment and lumbosacral segment were 0.122 卤0.120 0.211)cm 卤0.074 卤0.211)cm and 0.083 卤0.096 cm ~ (-1) respectively. The errors were 0.202 卤0.154 cm ~ (-1) and 0.283 卤0.187 cm ~ (Z), 0.136 卤0.127 cm ~ (2) 0.472)cm and 0.272 卤0.211 cm ~ (-1) respectively. The three directions were all smaller than the clinical error range (0. 3 cm, 0. 5 cm 路m ~ (-1), 0. 5 cm 路cm ~ (-1), the difference was statistically significant. In the head and neck segment, there was no significant difference between the two groups (P 0.05). The head and neck segment of the head and neck segment was composed of ttio -13.091t ~ 5.598t ~ (-1) -11.423 ~ (th) P 0.05, T ~ (17. 814) ~ 13.325 ~ t ~ (-4.699) T ~ (0.05), and the lumbosacral segment ~ (33. 632) t ~ (-8.974t) ~ 8.390m ~ (th) P 0.05 ~ (th). There was no difference in the X axis Y axis and Z axis between children and adults in the head and neck segment, thoracic segment and lumbosacral segment. There was no difference in the direction of X axis between head and neck segment, thoracic segment and lumbosacral segment. Conclusion: a new method for supine position fixation with head and body type fixation plate is used in CSI. It has the advantages of low error, convenient operation, higher degree of compliance and comfort, and can be used in children and adults.
