To perform dynamic stereotactic radiotherapy, a number of modifications to the commercial linear accelerator were required and these are described in this report. A couch drive system was added to rotate the couch in synchrony with the gantry. A high dose rate beam for this technique is acquired through a head modification, which allows easy removal of the radiation field flattener. Because of these modifications, a number of changes and additions were required to the linac interlock system, including a complete new chain of interlocks for use with the stereotactic technique.
为了进行动态立体定向放射治疗，需要对商用直线加速器进行一些改进，本报告将对此进行描述。增加了一个治疗床驱动系统，使治疗床与机架同步旋转。通过对机头进行改造获得了适用于该技术的高剂量率射束，这使得可以轻松移除辐射野均整器。由于这些改进，直线加速器联锁系统需要进行一些更改和添加，包括一套全新的用于立体定向技术的联锁链。
