案例|GE LOGIQ P6 彩超维修

admin

1.1 故障现象

GE LOGIQ P6机器所有探头在彩色多普勒工作模式下有干扰。

1.2 故障分析及排除

LOGIQ p6 机器板块结构简单，板块功能集成度高，该机器彩色多普勒处理功能在SYSCOM主板上，一般出现该种干扰考虑探头本身故障、外界干扰或者SYSCOM主板以及APS电源导致。

由于该机器所有探头均有干扰，所有探头均出现故障可能性很小，先考虑其它故障可能。把机器推到另一楼层房间中进行测试，仍存在干扰故障，排除外界干扰可能。APS电源故障有可能导致机器接入电压产生干扰，更换测试后排除APS电源故障可能。最后更换SYSCOM主板，机器启动正常工作，所有探头进入彩色多普勒工作模式均未再出现干扰现象，故障排除。

 总结

GE LOGIQ P6由于其板块结构较为简单，因此维修难度相较于其它超声机器要低。维修时主要根据机器具体故障表现以及机器工作原理分析故障部位并采取相应处理措施，对于较难分析判断故障部位的情况则应细心逐步排查，切忌胡乱尝试性维修。
