三维适形放射治疗技术的应用探讨

Application of 3D-CRT Technique

三维适形放射治疗(3D-CRT)是一种精确的放射治疗手段,三维适形放射治疗技术的合理应用,大大提高了肿瘤局部控制率,减少了放疗反应和后遗症。放射治疗师对放射治疗操作方法的改进,保证了治疗的重复性,明显提高了放射治疗的准确性及疗效,为三维适形放射治疗的顺利进行提供了有利的保障。

3-dimensional conformal radiotherapy（3D-CRT） is used as a precision radiotherapy treatment.Applying it properly can significantly increase tumor control rate,decrease the side effects and lingering effects of radiotherapy.The radiation therapy technician improves techniques and operation methods of 3D-CRT persistently,including the body posture fixation,CT imaging in the position localization and radiotherapy positioning.Then the reproducibility of radiotherapy is ensured,and the accuracy and effectiveness of radiotherapy is remarkably increased.In addition,the radiation therapy technician supplies better guarantee in the 3D-CRT process.
