  • 简介:目的:探讨GELightSpeedRT型CT模拟及NucletronSIMULIXHQ型模拟定位在头颈部肿瘤IMRT靶区治疗中心位置校正方法及各自优势。方法:抽取60例采取头颈肩热塑网膜固定的头颈部肿瘤IM-RT患者随机分成两组,利用DRR正侧位图像在模拟定位下校正位置30例,利用中心层面的横断面图像在CT模拟下复位30例。分别测量在X(左右)、Y(头脚)、Z(前后)三个方向上校位中心与治疗中心的位置差别,记录三个方向上的误差为Ex、Ey、Ez。结果:误差整理分为三个等级范围Ea≤±1mm,±1mm±2mm。CT模拟校正中心时X方向上各误差等级范围例数依次为8(26.7%)、18(60.0%)、4(13.3%);Y方向上为19(63.3%)、8(26.7%)、3(10.0%);Z方向上为9(30.0%)、14(46.7%)、7(23.3%)。模拟定位校正中心时X方向为6(20.0%)、19(63.3%)、5(16.7%);Y方向上为9(30.0%)、18(60.0%)、3(10.0%);Z方向上为8(26.7%)、14(46.7%)、8(26.7%)。三个方向上CT模拟校正中心的平均误差分别为1.39mm、0.53mm、1.48mm;模拟定位分别为1.51mm、1.43mm、1.66mm。60例患者首次治疗时按照校正后的中心进行摆位,经加速器治疗前IGRT验证其三维方向上的误差均控制在±2mm以内。结论:对于采取头颈肩热塑网膜固定的头颈部肿瘤IMRT患者,无论是采取CT模拟复位还是模拟定位复位,其三维方向上整体最高只有40%的患者位移精度在1mm以内,所以为确保患者的治疗,IMRT计划出来后进行位置验证和修正是非常有必要的;三维方向上,CT模拟和模拟定位的复位平均精度都控制在2mm以内,所以两种设备都可以适用于IMRT计划的位置验证,有利于提高模拟的使用率和工作效率;CT定位复位方法在三维方向上平均精度高于模拟定位的平均精度,主要是在Y方向上的差异明显。
