min-height: 1em; white-space: normal; line-height: 2em; box-sizing: border-box !important; word-wrap: break-word !important;">彩超设备是一种极为先进的诊断系统,其采用的大量的科学技术,例如核磁共振技术、Pureware纯净波探头技术及组织差异校正技术等;一般彩超系统包括以下几个部分:探头、前段信号采集部分、电源模块控制部分、信号图像处理部分及输出显示部分。下面以飞利浦彩绸为例进行详细介绍。</p><p style="max-width: 100%;

min-height: 1em; white-space: normal; line-height: 2em; box-sizing: border-box !important; word-wrap: break-word !important;">②彩超超声图像出现布纹状干扰。这是一种由多种因素引起的干扰故障,通常情况系对其判断需要采取排除法并以由简单到复杂为原则,只有这样才能迅速找出干扰因素;判断其干扰源应从三个方面考虑:仪器设备外部的电磁干扰;仪器设备内部的干扰;探头产生的干扰。故障排除方法:要先检查干扰是否来自设备外部,将室内的其他电气设备关闭,再观察彩超超声图像上是否存在干扰,如关闭电子读卡器电源后,图像上的干扰消失则表示该电子读卡器对设备产生了电磁干扰;如将读卡器靠近探头,设备上的干扰信号越强;这时可选择一个电磁兼容性能较好的读卡器,干扰即可消失,仪器恢复正常。</p><p style="max-width: 100%;

word-wrap: break-word !important;"  /></strong>无法正常启动故障维修:应按照相关操作说明,断开设备前端并切断主电源至设备前端电源的接头,以维修手册短接电路,再开机测试;如设备前端存在故障则能够正常开机;如设备前端无故障则无法正常开机。采用同样方法检测设备后端。检测结果显示前后端均无故障,则对设备主机电源进行检测,确定故障存在于主机电源。在确定故障后,首先拆开主机电源,调整万用表至测量电压状态,随后检测后端电源分配板SPD,再输入+12V直流电压后,如发现电源分配板无任何输出,仔细观察后发现是后端电源分配板连接的场效应管出现裂痕,这时取同场效应管替换之前的场效应,再焊接好场效应管元件及电路板损害。&nbsp;</p><br style="max-width: 100%;
