电子直线加速器因其能量高,射线深部剂量大,皮肤反应相对较小,同时可产生不同能量的X线与电子线,因此已成为治疗肿瘤的重要手段。但同时因其电路结构复杂,又存在高压、静电、强磁场等原因,所以故障发生率相对较高。下面是我们在日常工作中遇到的故障维修实例介绍,供同仁参考。 Because of its high energy, deep dose of radiation, skin reaction is relatively small, at the same time can produce different energy X-ray and electron beam, it has become an important means of treatment of cancer. But at the same time because of its complicated circuit structure, there are high voltage, static electricity, strong magnetic field and other reasons, so the incidence of failure is relatively high. The following is an example of fault repair that we encountered in daily work, for my colleagues in reference.
