15px;">与排除机器计算机部分的软件平台是window，蓝屏报错主要与window软件和其所依赖的计算机硬件有关；与超声形成相关的电路板如出故障，通常会出现专门的报错代码，而且不会显示蓝屏的底色。针对此故障现象，首先应考虑是计算机内部出的问题，即系统软件出错，或硬盘损坏。排除此故障的方法为：拆开硬盘，用效率源软件检查硬盘可发现硬盘有小部分坏道。</span></p><p><span

15px;">在机器探头打上耦合剂后扫描，发现图像暗线的边缘比较明显，根据超声图像形成和彩超结构的原理分析，故障原因可能是对应的探头晶片出现问题或对应的通道有问题；切换不同探头进行测试发现，每个探头均有同类的暗线存在，每个探头同时有晶片损坏的可能性较小，可以排除探头损坏，而故障可能发生在对应的通道板上。GE Logiq9彩超前端有8块通道板，执行对应的超声波发射和接收以及A/D转换，8块通道板对应不同的探头通道，每个板处理24个通道。在显示器图像上标记好对应的暗线位置，关机，交换通道板的位置，当交换到第4块通道板时，图像上对应的暗线位置发生移动，再用另一块通道板与第4块通道板交叉检查，判断故障出现在第4块通道板。</span></p><p><span style="font-size:
