东芝Aquilion one CT维修案例分析与解决

Toshiba Aquilion one CT Maintenance Case Analysis and Solution

本文分析了东芝Aquilion one CT的三例故障,分别为出现曝光旋转时,机架噪声大;重建柜内QFPGA功能板件损坏,冠脉重建时出现报错;球管损坏,设备曝光失败,报“Over mA”故障。采用了逐步排除法、仔细观察法、软件数据分析法等检修方法,通过分别对机架轴承添加润滑油、更换QFPGA板件、更换同型号球管进行参数调试校准后,故障得到解决。这些检修方法的运用及相应解决问题的方案,给同行提供了参考与借鉴,对于提高维修效率,为医院节省维修成本和保证医院相关科室工作正常开展,发挥了重要作用。

This article analyzed three failures of Toshiba Aquilion one CT.They were the loud noise of the rack when the exposure rotation occured;the QFPGA function board in the reconstruction cabinet was damaged,and an error occured during coronary reconstruction;the tube was damaged and the equipment failed to be exposed,and reported“Over mA”.After adopting maintenance methods such as step-by-step elimination method,careful observation method,and software data analysis method,the faults were solved by adding lubricating oil to the rack bearing,replacing the QFPGA board,and replacing the same type of tube for parameter debugging and calibration.The application of these maintenance methods and corresponding problem-solving programs have provided reference and reference for colleagues,and play an important role in improving maintenance efficiency,saving maintenance costs for the hospital,and ensuring the normal operation of related departments in the hospital.
