手提式X射线像增强仪

A Portable X-ray Image Intensifying Device

描述了一种可以用于医学和工业领域的手提式X射线透视队。包括其总体技术条件的确定及主要组件的设计。仪器采用了液体和固体的绝缘材料、含微焦点X射线管的射线源和CSI阴极的双近贴射线像增强器，有复合灌封结构形式的射线源组件，能在体积、机械性能等多方面条件限定下，稳定提供30UA、55kV（DC）强度下的X射线和分辨力5lp／mm、最大输出亮度30cd／m_2以上的透视图象。装置对漏射线的屏蔽符合国家相应标准的要求。

A portable X-ray image intensifying device which can be used in medical andindustrial areas is described. The ensuring of the overall specification and the design of mainmodules are included. The liquid and solid state insulants,a X-ray radiant containing a miniature X-ray tube,and a wafer radiation intensifier having a CsI cathode are used in the device.The radiant of the device assembly is fitted with the compound structure by pouring inSLllants.According to the structure, the radiant can steadily supply 30 pA, 55 kV (DC)Xdsray radiationand above 5 lp/mm, 30 cd/m' image under the restriction in size and mechanical strcngth. Theperformance screening inutile ray fills the requirement of corresponding nation criteria.
