摘要
本文对研制的5 MHU的CT球管进行了测试,球管工作电压140kV,热容量5MHU,大焦点阳极功率48kW,具有大小焦点两种工作模式,大焦点0.7mm×1.6mm,小焦点0.6mm×1mm,并在CT机上进行测试,球管与CT机匹配良好,成像质量优良。此外,还对测试过程中出现的失效问题进行了探讨。
Test results of the 5 MHU CT tube are described.The heat-absorption capacity of the tube is 5MHU and the working voltage is 140 kV.The tube can work at large and small focal spot mode,the large focal spot is 0.7mm×1.6mm and the small one is 0.6mm×1mm,the anode power in large focal spot mode is 48 kW.The tube matches with the CT machine well and excellent topography images are obtained.In addition,tube failures in test are discussed.
