Electron radiation therapy has been used to treat shallow tumours for more than 50 years. Although every radiation therapy centre is equipped with linear accelerators generating electron fields, this treatment method has always been hampered by technical difficulties related to field collimation. Conformal field shaping is critical to spare normal tissues. We have developed an electron multi-leaf collimator prototype that automatically shapes the beam and generates sequences of therapeutic fields through a remote-control graphical user interface. We will develop precise dose calculation algorithms that will be part of a fast iterative treatment planning system.

电子放射疗法用于治疗浅层肿瘤已有 50 多年的历史。尽管每个放射治疗中心都配备了产生电子场的直线加速器，但这种治疗方法始终受到与场准直相关的技术困难的阻碍。适形场整形对于保护正常组织至关重要。我们开发了一种电子多叶准直器原型，可通过远程控制图形用户界面自动调整光束形状并生成治疗场序列。我们将开发精确的剂量计算算法，该算法将成为快速迭代治疗计划系统的一部分。
