Abstract：This paper analyzed two cases of Siemens Definition dual source CT fault in practical application in detail that made the
machine unable to work normally, which were the faults of liegen master and universal master stationary (UMAS). Through analysis
and investigation of the fault in-depth, the software program and only part of the UMAS internal memory card were used to solve the
fault quickly and effectively with the minimum maintenance cost. Through the scientific and reasonable, innovative and independent
maintenance methods to solve the problems, a lot of funds can be saved for the hospital department, the stable operation of the
machine is ensured, and the work efficiency of the department is improved.
