据不完全统计,我国目前拥有 CT 机5000余台,伽马刀约200台,医用加速器钴-60治疗机等放疗设备1400余台,X 射线机约7万余台。从事放射诊断和治疗的医疗机构约5万个,医用辐射的危害也在增长,放射诊疗质量与安全状况堪忧。每年由于放射诊疗技术使用不当,造成患者过量照射或医源性放射损伤事故时有发生。据对我国12个省市医院中292台放射治疗机输出量指标调查显示,合格率仅为64%。有关专家指出,缺乏医学防护管理法规,监督管理混乱,专业队伍后继乏人的状况亟待转变。
According to incomplete statistics, China currently has more than 5,000 CT radios, about 200 Gamma scalpels, over 1,400 sets of radiotherapy equipment such as cobalt-60 medical accelerators and about 70,000 X-ray radios. There are about 50,000 medical institutions engaged in radiological diagnosis and treatment, the harm of medical radiation is also increasing, and the quality and safety of radiological diagnosis and treatment are worrisome. Each year due to improper use of radiological techniques, resulting in patients with excessive radiation or iatrogenic radiation injury accidents have occurred. According to a survey of 292 radiotherapy machine output indicators in 12 hospitals in China, the pass rate was only 64%. Experts pointed out that the lack of medical protection and management laws and regulations, supervision and management chaos, lack of succession of professional contingent of people in urgent need of change.
