射束强度受调节的适形放疗法是一种先进的放射治疗方法，它使用一组强度可独立控制的笔射束，通过旋转或多野静态照射肿瘤靶，使射野内高剂量分布形状在三维方向上与肿瘤靶的形状一致，同时尽可能地减少了靶区周围健康组织的照射剂量，从而大大提高放射治疗的治疗增益比，促进肿瘤的局部控制。本文系统地阐述了强度受调节的适形放疗的优势与治疗计划理论。
Beam-modulated conformal radiation therapy is an advanced radiation therapy that uses a set of pencils of beam intensity that can be controlled independently by rotation or multiple field static irradiation of the tumor target to allow the high dose distribution in the field to be three-dimensional Direction and the shape of the tumor target, while reducing the irradiation dose of healthy tissue around the target area as much as possible, thereby greatly improving the therapeutic radiation ratio of radiation to promote local control of the tumor. This article systematically expounded the strengths of adjusted intensity conformal radiotherapy and treatment planning theory.
