<h3 style="margin-top: 13px; margin-bottom: 5px; font-size: 18px; font-family: 'Microsoft YaHei', Verdana; color: rgb(51, 51, 51); line-height: 25px; white-space: normal; background-color: rgb(255, 255, 255);">盲区问题</h3>普通探头上安装穿刺架，穿刺针在穿刺架上进针时，存在一定的盲区，这段盲区内针体在显示器上无反射，因此在穿刺时需要避开重要的血管和器官，对于线阵探头需要特别注意。 <h3 style="margin-top: 13px; margin-bottom: 5px; font-size: 18px; font-family: 'Microsoft YaHei', Verdana; color: rgb(51, 51, 51); line-height: 25px; white-space: normal; background-color: rgb(255, 255, 255);">穿刺针偏离扫描平面问题</h3>探头的短轴方向聚焦声束一般只有数毫米，安装穿刺架时，若有偏斜，就要偏离扫面平面，屏幕上就显示不出针体的反射。所以安装时一定要认真仔细，尽量做到使穿刺针处于短轴的中心垂面内，对于较长的线阵扫描探头来说，要做到穿刺针正好处于短轴的中心垂面内是比较困难的，这在诊断中有时会造成伪像，尤其对于较深部位的脏器，更是如此。 <img data-s="300,640" data-type="jpeg" src="http://mmbiz.qpic.cn/mmbiz_jpg/dx3KibwtDhvdnZWV3ueduB24nd5m9dA01bhc6mjob4VoLcXWjTNMQKaIAmCom4zftpjVNx4MAlvLcjtqssAvtRg/0?wx_fmt=jpeg" data-ratio="0.6633333333333333" data-w="300" /> <h3 style="margin-top: 13px; margin-bottom: 5px; font-size: 18px; font-family: 'Microsoft YaHei', Verdana; color: rgb(51, 51, 51); line-height: 25px; white-space: normal; background-color: rgb(255, 255, 255);">穿刺架的安装调整</h3>为了检查穿刺架的安装情况，可用下图的方法来检查安装情况并调整。水槽的底部敷设吸声橡胶，在距睡眠一定距离处（例如150px）安装一块穿刺目标，例如可以做一只半径约为4mm、厚度约为5mm的透声橡胶块，在水面上来回变动探头位置，使屏幕上的穿刺引导线穿过目标块图像的中心并使目标状态最清晰，这是将探头固定，使图像保持最佳状态。然后反复将穿刺针沿穿刺架的的路径向目标位穿刺，若穿刺针每次都沿引导线刺中目标，说明穿刺架的安装良好；若针尖每次偏离引导线的角度是固定的，则说明穿刺架安装倾斜或引导线的角度选择不对，应找出原因予以纠正；若针尖每次偏离引导线的角度和方向不固定，则说明导向器安装和松动现象，应将其调整。有时需经反复调整，直到针尖清晰且每次都沿引导线推进为止。 <span style="max-width: 100%;
