摘　　要：随着医院超声设备的发展以及超声多普勒效应在彩色超声的应用,医院复杂的用电条件相应电磁干扰,给超声设备的图像质量带来不良影响,加大了超声设备操作人员的工作难度,并且覆盖了有用的图像信息。在经过实例的分析和处理,发现了不间断电源(UPS)和稳压电源的选择以及标准电线的实现方式,都是解决电磁环境对彩色多普勒超声图像影响的有效途径。With the development of ultrasonic instrument and ultrasound Doppler effect in the application of color ultrasound, the hospital complex power conditions corresponding to electromagnetic interference, ultrasound equipment to bring adverse effects on image quality, increased the difficulty of the operation of ultrasound instrument operators and overlays the useful image information.Through the analysis and processing of the example, it is found that the selection of the UPS and the regulated power supply and the way of realizing the standard wire are the effective ways to solve the electromagnetic environment impact on the color Doppler ultrasound image.
