我国医用核仪器的研制是从七十年代起步的,据不完全资料统计,目前至少有30多个单位生产此类仪器。261、262、759厂,核海公司和日环仪器厂是我国生产医用核仪器的几个大厂。目前我国γ放射免疫计数器、放射性活度计、液体闪烁计数器、甲功仪、肾功仪、骨密度仪……,已普及到县级医院。γ照相机已能批量生产、单光子发射计算机断层扫描装置已由组装国外散件配自产图像处理机发展到自己研制出样机阶段,形势喜人。 为了使各生产单位在医用核仪器的设计和生产过程中有一个共同遵循的准则,以确保产品的质量,全国核仪器仪表标准化技术委员会组织有关单位和专家制定了EJ298—87《人体甲状腺摄碘率测定仪探头技术要求》、GB/T10255—88《γ放射免疫计数器》、GB10256—88《放射性活度计》、GB/T10259—88《液体闪烁计数系统》和EJ441—89《肾功能仪铅准直探头》等5个标准。 笔者在经过对30余个医用核仪器生产单位和30余个医院的函调,及对261厂、262厂、核海公司、中国计量院等生产单位和协和、肿瘤医院等使用单位的重点走访的基础上撰写了此文,以供今后制修订和贯彻实施标准作参考。
The development of medical nuclear instruments in our country started from the 1970s. According to incomplete statistics, at least 30 units currently produce such instruments. 261,262,759 factories, nuclear companies and Rinnai Instrument Factory is China’s production of medical nuclear instrument several big factory. At present, our country γ radioimmunoassay, radioactivity meter, liquid scintillation counter, thyroid meridian, kidney meridian, bone densitometer ..., has spread to county hospitals. gamma camera has been able to mass production, single-photon emission computed tomography device has been assembled from foreign spare parts with self-produced image processor to develop their own prototype stage, the situation is gratifying. In order to ensure that all production units have a common principle in the design and production of medical nuclear instruments in order to ensure the quality of their products, the National Nuclear Instrument Standardization Technical Committee has organized relevant units and experts to develop the EJ298-87 “ GB / T10255-88 ”gamma radioimmunoassay“, GB10256-88 ”radioactivity meter“, GB / T10259-88 ”liquid scintillation counting system“ and EJ441-89 ”kidney function lead Collimation probe "and other five criteria. After more than 30 medical nuclear instrument production units and more than 30 hospital correspondences, and the 261 factory, 262 factory, nuclear company, China Metrology Institute and other units and the Concord, Cancer Hospital and other units to use key visits Based on the article written for future revision and implementation of standards for reference.
