立体定向适形放射外科治疗 (BodyStereotacticConformalRadiotherapy)就是利用直线加速器产生的X线 ,应用多叶准直器进行射束成形 ,产生与肿瘤外形轮廓一致的射束形状 ,对肿瘤进行分次、大剂量、多角度的非共面适形照射。本文简要介绍与体部立体定向适形放射外科治疗有关的几个技术
Stereotactic radiotherapy (BodyStereotacticConformalRadiotherapy) is the use of linear accelerator to produce X-ray, the application of multi-leaf collimator beamforming, the shape of the tumor contour with the same beam shape, the tumor was divided, high dose, Multi-angle non-coplanar conformal irradiation. This article briefly introduces several techniques related to stereotactic conformal radiosurgery
