                    <p style="line-height: 2em;"><span style="font-size: 14px;">&nbsp;目前彩超设备品牌众多，如何在价位、性能、用途等方面选择到自己钟意的机器，现在就彩超设备采购参数方面作相关阐述：</span></p><br  /><p style="line-height: 2em;"><span style="font-size: 14px;">1.应用临床范围及其侧重点：超声应用于腹部、心脏、浅表器官、外周血管、腔内、术中及造影等。目前分类主要有全身机、腹部妇产科用机、浅表器官血管用机、心脏机，要根据需要寻求品牌及型号。如GE
VIVID系列在心脏方面擅长；麦迪逊机器腹部妇产科为强项、心脏方面功能较弱。日本品牌机器在腹部方面成像质量尤佳，但由于其技术短处，心脏成像理想机型较少。<br  /><br  />2.探头：种类有凸阵、线阵、相控阵、腔内、容积、心腔内导管探头、经食道探头。是否具备宽频多频可变频技术，是否均支持谐波成像功能。<br  /><br  /><img data-s="300,640" data-type="jpeg" src="http://mmbiz.qpic.cn/mmbiz_jpg/dx3KibwtDhvcNX6gqZribk48J22dWsxBQwUhtDvQgEpZEBbRgORy2pPUicXkvxa37KQF6bLJMCwpjxGNZibQ3wuUxg/0?wx_fmt=jpeg" data-ratio="0.7423857868020305" data-w="788"  /><br  />3.二维灰阶成像系统<br  />1）数字化波束形成技术<br  />2）发射／接收通道数<br  />3）接收超声信号动态范围<br  />4）扫描线密度<br  />5）探测深度<br  />6）帧速率<br  />7）是否支持组织及造影谐波成像<br  />8）复合成像技术<br  />9）组织多普勒<br  />10）编码激励和各种脉冲波控制成像技术<br  />11）灰阶血流成像技术<br  />12）线阵探头梯形成像技术<br  />13）宽视野成像技术<br  /><br  />4.频谱多普勒成像系统<br  />1）多普勒类型：PW、CW、HPRF等<br  />2）显示方式<br  />3）电影回放时间<br  />4）测量速度：最大／最小<br  /><br  />5.彩色血流成像系统<br  />1）血流成像方式<br  />2）彩色血流显示方式：速度图、能量图、速度能量图等<br  />3）彩色显示角度<br  />4）彩色显示帧频<br  /><br  />6.三维成像功能<br  />1）实时4D立体成像技术<br  />2）三维成像：组织、血管、表面<br  /><br  />7.组织优化及处理技术<br  />1）像素优化、斑点噪声去除技术<br  />2）自适应扫描控制技术<br  />3）自动组织显示优化技术<br  /><br  />8.测量分析功能<br  />1）一般测量功能<br  />2）多普勒血流测量及分析<br  />3）心脏功能测量及分析<br  /><br  />9.数字化数据和图像存储／管理／传输系统<br  />1）文件信息管理系统：报告文件储存、图像储存格式选择、存储媒体：HD、FD、MOD、CD、DVD。<br  />2）数字通信传输系统：视频打印机接口；外接监视机接口；录像机接口；DIMCOM3.0接口；USB接口。</span></p><p><br  /></p><p style="max-width: 100%;
