word-wrap: break-word !important; box-sizing: border-box !important;"  />安装安装前的准备工作</p><p><img data-s="300,640" src="http://mmbiz.qpic.cn/mmbiz/A1DicCH9Vl6MYAEPWTib8tjxcvx0icbN5kqz5dicyaC7bIAWFLrH3BQ68tzfrZALXuPNjydAor7M81cXE231USyLJA/0" data-ratio="0.7509881422924901" data-w=""  />对机房的环境要求</p><p><br style="max-width: 100%; word-wrap: break-word !important; box-sizing: border-box !important;"  />(1)工作温度一般要求10℃-28℃；</p><p>(2)湿度一般要求35％-80％，要求机房内安装独立的空调，不提倡用中央空调；</p><p>(3)电源要求：电源容量由球管容量决定，我们的球管是1MHU的，要求50kVA即可；电源电压：本机要求三相电源，相间电压380V；电源频率：50Hz±0.5Hz；要求电源波动幅度：土10％；接地：要求独立接地.<br style="max-width: 100%; word-wrap: break-word !important; box-sizing: border-box !important;"  /><br  /></p><p>机房设计：<br style="max-width: 100%; word-wrap: break-word !important; box-sizing: border-box !important;"  />机房设计要求布局合理即可，掌握一个原则--方便病人就诊，方便医生工作，防护好。这其中需要注意几个问题：</p><p>(1)线槽尽量做得稍宽一些，我们做得为20×70cm；</p><p>(2)铅玻璃为80(高)X100(宽)；</p><p>(3)防护(包括墙体、铅玻璃及窗户)要相当于2mm铅当量。</p><p><br  /></p><p>安装：由于我们是旧机器的拆迁，所以Gantry内的东西基本没动，再加上安装前的准备工作做的比较到位，所以安装起来相应简单一些。为防止Gantry内的球管及逆变器组件等在搬运过程中旋转而引起损坏，要用特定工具将其固定起来，搬动到安装地点再将其拆下来。</p><p><br  /></p><p>在机器的Gantry及Table的定位过程中，我们用厂家提供的图纸在地上仔细定位，反复校正，确认无误后，才开始用电钻打孔，将Gantry及Table对准放好后，用膨胀螺丝固定好，在这过程中还应注意Gantry及Scan Table的水平情况，使其尽量水平。配线：这项工作需要仔细来完成，按照拆卸时的记录，仔细的接好各接头，接完后，互相检查一下是否正确，电源留到最后去接。</p><p><br style="max-width: 100%; word-wrap: break-word !important; box-sizing: border-box !important;"  />调试：由于是旧机器，各项系数都已预先设置好，调试相对比较简单一些。</p><p>(1)确认电压、地线、相序无误，尤其是相序非常重要，一定要测对，否则会引起Gantry反转，损坏机器；</p><p>(2)机械动作的确认，包括Gantry扫描角的确认，Table的升降，Table Top的前后运动，Tile及Scanner的旋转等</p><p>(3)调试：由于是旧机器，其各项参数的调试在装机时皆已完成，无须重新测试，但有一项必须重新校正--体模校正，这是非常重要的一项。</p><p>做校正时应注意：</p><p>(1)先做各层厚的air calibration(空气校正)；</p><p>(2)按照体模直径由小到大顺序作校正；</p><p>(3)找好中心(误差应小于等于0.lmm)。以上三步完成后再作CT值的校正，通过校正来达到CT机各通道的一致性，使CT值趋于一致，减少伪影。</p><p style=""><span style="max-width: 100%;
