Title
(EN) Systems and methods for providing radiotherapy treatment
(ZH) 用于提供放射疗法治疗的辐射治疗机和系统
Abstract
(EN)
In one embodiment, radiotherapy treatment is provided to a target volume of a patient by configuring a multileaf collimator of a radiation treatment machine in a first orientation so as to form an actual aperture having a first orientation, delivering radiation to the target volume through the actual aperture while in the first orientation with a single pass along an arcuate path centered on the target volume, configuring the multileaf collimator in a second orientation so as to place the actual aperture in a second orientation that is different from the first orientation, and delivering radiation to the target volume through the actual aperture while in the second orientation with a single pass back along the arcuate path such that a relatively large cumulative dose of radiation is delivered to the target volume through a virtual aperture created by an area of overlap between the first and second actual aperture orientations.

(ZH)
在一个实施方案中,通过以下来为患者的靶区提供放射疗法治疗:将辐射治疗机的多叶准直器配置在第一方向以便形成具有第一方向的实际孔径,沿着以靶区为中心的弧形路径以单次通过而穿过在第一方向时的实际孔径将辐射递送至靶区,将多叶准直器配置在第二方向以便将实际孔径放置在不同于第一方向的第二方向,并且沿着弧形路径向回以单次通过而穿过在第二方向时的实际孔径将辐射递送到靶区,使得穿过由在第一实际孔径方向和第二实际孔径方向之间的重叠区域创建的虚拟孔径将累积的相对大的辐射剂量递送到靶区。
