摘要 提出一种快速定位检修医用直线加速器和螺旋断层治疗系统“GAS”连锁故障的有效方法。采用带红外线的制冷剂泄漏检测仪结合肥皂水泡进行检漏;采用砂纸、锉刀轻轻打磨漏点及周围5 mm 宽的波导表面,再利用大功率150 W的电烙铁进行锡焊补漏。快速定位检测出泄漏点,补漏后的波导管使用12年未发现泄漏。有了这一方法,医用直线加速器和螺旋断层治疗系统“GAS”联锁故障的检修并不难。
Abstract：In this paper, an effective method was proposed for rapid positioning and repair of medical Clinac and helical tomotherapy “GAS” interlock fault. The infrared refrigerant leakage detector was combined with soap bubbles for leakuseage detection. The sandpaper and file were utilized to gently grind the leakage point and the surrounding 5 mm-wide waveguide surface,and then the high-power electric soldering iron of 150 W was adopted to make up for the leakage. The leakage point was detected by rapid positioning,and no leakage was found in the waveguide after 12 years of use. This approach can significantly reduce the difficulty in the repair of the Clinac and helical tomotherapy"GAS" interlock fault.
