综述:对患者进行检查或治疗的仪器、装置和设备质量保证措施的实施,由射线防护条例确定。作为例子,列 Gieβen(纪森)大学附属医院的 SL25直线加速器进行的质量保证措施作了介绍并对其耗费的工作量作了估计。从实验结果来看,用于治疗患者的时间可能降低到整个工作时间的75%。剩下的时间则是进行保养和实施质量保证措施所必须的。 Summary: The implementation of quality assurance measures for instruments, devices and equipment used to examine or treat patients is determined by the Regulations on Radiological Protection. As an example, the quality assurance measures performed by the SL 25 linear accelerator at the Gießen University Hospital were introduced and the amount of effort was estimated. From the experimental results, the time used to treat patients may be reduced to 75% of the working hours. The rest of the time is necessary for maintenance and quality assurance measures.
