根据γ一刀的原理,我们利用~(60)CO放疗和模拟定位机,设计并研制了与之配套的准直仪及定位器。通过对16例脑深部小型肿瘤及AVM的等中心放疗,确立了靶点定位的方法,放射剂量的计算以及间歇性等中心放射治疗的设计.
According to the principle of γ-knife, we used ~ (60) CO radiotherapy and simulated positioning machine to design and develop the collimator and positioner. Through the 16 cases of deep brain tumors and AVM iso-center radiotherapy, established the method of target location, radiation dose calculation and intermittent isocentric radiation therapy design.
