摘　　要：目的:探讨婴幼儿放射防护装置与多种方法配合使用以减少辐射剂量的临床应用价值。方法:在婴幼儿放射防护装置检查床上,使用3块倒U形有机铅玻璃罩和垂直铅挡板组成相对独立的空间,通过调节有机铅玻璃罩和垂直铅挡板不同位置以达到辐射防护的目的,并与婴幼儿体位固定支具,采用监控摄像头、调节照射野、靶-片距及室内温度等方法采取低剂量方法,最大限度降低患儿辐射剂量。结果:通过婴幼儿放射防护装置与辅助设备的使用,有效提高了在CT扫描、DR摄影等各种患儿检查时的成功率,确保影像质量,避免重复检查,减少了患儿辐射剂量。结论:有效减少患儿辐射剂量和其他人群的照射,遵循X射线检查的正规化和辐射防护最优化原则,在获得必要诊断信息的同时使受检儿童受照剂量保持在合理的最低水平。Objective： To explore the clinical application value of infant radiation protection device combined with a variety of methods to reduce radiation dose. Methods： Three plumbic bafflers and ＂inverted u-shape＂ organic plumbic glasses on the check bed of radiation protection device set up a perfect relatively independent space. The location of organic plumbic glasses and bafflers were regulated for radiation protection, at the same time, combined with a variety of methods to reduce radiation dose, for example infant position stabilizing brace, securitycamera, exposure field, target-film d_istance, environmental factors,low dose, etc. Results： Through the use of the new infant radiology protective device and ancillary equipment, the achievement ratio of children＇s CT and DR examination was effectively improved, the repeated checking was avoided, the image quality was secured, and x-ray irradiation of infants was reduced. Conclusion： The radiation doses of the infants and other population were reduced, and the justification and optimization principles of x-ray examination protection, in order to reach and keep a reasonably minimum level for the inspected children＇s doses at the same time keeping the necessary diagnostic information.
