AI Technical Summary
Technical Problem
In existing gamma-ray stereotactic radiotherapy, target selection is difficult, resulting in time-consuming treatment planning and uneven dose distribution. In particular, it is difficult to match the target boundary with the dose field when the tumor shape is complex.
Method used
The target area to be treated is divided into multiple sub-target areas, and the set of control points for the treatment bed and radiation delivery parameters corresponding to each sub-target area are determined. A treatment plan is generated by the relative and continuous movement of the treatment bed and the focal point of the radiation beam.
Benefits of technology
It shortens treatment time, improves dose field conformity and treatment plan quality, and achieves more refined radiotherapy control.

Abstract
本公开提供一种治疗计划生成方法、电子设备和存储介质，涉及医疗技术领域，尤其涉及放射治疗技术领域，用于解决现有技术治疗计划生成的质量较低的问题。该方法包括：获取待治疗靶区的图像、一组一个或多个优化目标以及待治疗靶区的轮廓信息，一组一个或多个优化目标包括待治疗靶区的期望剂量分布；根据待治疗靶区的轮廓信息，将待治疗靶区划分为多个子靶区；确定每个子靶区对应的治疗床控制点集及与治疗床控制点集中的每个治疗床控制点相关联的一个或多个辐射递送参数，其中，治疗床控制点集涉及治疗床与辐射射束聚焦点之间的相对持续移动；基于一组一个或多个优化目标，优化待治疗靶区中的治疗床控制点及相关联的辐射递送参数，生成治疗计划。
