Abstract：The malfunctions of medical devices resulting from EMI (Electromagnetic Interference) in our
hospital were analyzed, including the EMI of high-frequency electric knife on the temperature-controlling
blanket, the EMI produced by electric welding machine on the CRT (Cathode Ray Tube) screen of CT
workstation, and the EMI of the power supply line on the echocardiography probe head. The reasons for
EMI phenomena were identified through analysis, and the different anti-EMI measures were taken. The
results showed that three cases of EMI problems were well solved.
