15px;"></span></p><p><strong><span style="font-size: 15px;">前言</span></strong><span style="font-size: 15px;"></span></p><p><br  /></p><p><span style="font-size: 15px;">Sequoia 512彩色超声诊断系统是西门子2000年以后推出的智能化超声诊断系统。</span><span style="font-size: 15px;">集成了2D﹑3D和实时4D成像模式，实现了设计和语音控制﹑扫描﹑聚集﹑优化等技术的智能化控制。</span></p><p><br  /></p><p><strong><span style="font-size: 15px;">故障现象</span></strong><span style="font-size: 15px;"></span></p><p><br  /></p><p><span style="font-size: 15px;">B超主机影像正常，电脑工作站软件操作界面的采集影像闪烁不定，并且覆盖一层垂直的带状干扰，图像无彩色。</span></p><p><br  /></p><p><strong><span style="font-size: 15px;">故障分析及处理</span></strong><span style="font-size: 15px;"></span></p><p><br  /></p><p><span style="font-size: 15px;">电脑工作站的影像故障，首先猜测可能是B超主机和电脑工作站之间的传输连接不好，通过检查，发现工作站是并口转接到S-VIDEO(S端子)上的，插拔S端子发现故障依旧。</span></p><p><br  /></p><p><span style="font-size: 15px;">在B超主机后面有BNC接口，连接上此接口后，发现图像彩色出现了，但其它故障依然存在。</span></p><p><br  /></p><p><span style="font-size: 15px;">询问操作人员获知机器曾被挪动过，接插口以前一直都是插在BNC接口上的。</span><span style="font-size: 15px;">B超机信号输出的S端子可能存在问题，也可能是该工作站视频采集卡的连接S端子处有问题，后更换视频采集卡发现有彩色，但是图像闪烁不定且覆盖一层垂直带状干扰，故障依然存在，得出B超的S端子没有信号输出。</span></p><p><br  /></p><p><span style="font-size: 15px;">出现此故障首先怀疑可能是电脑本身的问题。</span><span style="font-size: 15px;">于是退出青蓝公司的软件(该公司的提供的图像采集卡和软件)，直接进入采集卡的工作界面，发现采集卡本身显像和经过软件处理之后的图像一样存在着闪烁现象，可见是在软件处理之前就已经出现问题了。</span></p><p><br  /></p><p><span style="font-size: 15px;">排除了连接和PACS软件的原因，因为在工作站上能隐约看见实时影像，可知影像能够正常的传输到工作站，只是显示的方式和影像源不同，由此怀疑是图像格式设置的问题，进入格式设置界面，发现目前选项是NTSC制式，改选为PAL制式后，采集的实时影像和影像源的实时影像完全一致，故障排除。</span></p><p><br  /></p><p><strong><span style="font-size: 15px;">小结</span></strong><span style="font-size: 15px;"></span></p><p><br  /></p><p><span style="font-size: 15px;">NTSC是正交平衡调幅制，PAL为逐行倒像正交平衡调幅制，PAL和NSTC是两种不同标准的电视制式，PAL标准每秒25帧，电视扫描线为625线，NTSC标准每秒29.97帧，电视扫描线为525线。</span><span style="font-size: 15px;">我国采用625行的隔行扫描制，每帧图像分为两场。</span><span style="font-size: 15px;">我院超声诊断仪影像源传出的信号是PAL制式的，故障发生时设置的接收的标准却是NTSC制式，所以扫描的方式和增加脉冲信号的不同就导致了显示的影像不稳定且有带状干扰。</span></p><p style="max-width: 100%;min-height: 1em;letter-spacing: 0.544px;white-space:
