【摘 要】目的:探讨心磁图(MCG)在冠心病(CHD)诊断中的临床应用价值.方法:应用美国CardioMag Imaging公司生产的CMI-2409型心磁图仪,分别对383例冠心病患者(冠状动脉造影显示至少1支冠状动脉主要分支狭窄≥50%)和110例非冠心病患者(冠状动脉造影无狭窄)进行心磁图检查,对 ...

摘要： 心磁图是无创性记录和分析心动周期中由电活动所产生的电磁场成分和变化的方法,通过一个低温超导量子介入装置探测和量化心脏非常微小的磁信号,用于冠心病的诊断,并估计心肌病变.我院于2003年引进的美国CardioMag Imaging公司生产的CMI-2409型心磁图仪是 ...

cmi-2409型心磁图仪构造与检测方法 : (一)仪器的组成 cmi-2409型心磁图仪主要包括3个部分:①检查床:为双层带滑轮可移动检查床(图69-1);②信号采集装置(系统):由9个3×3距阵排列的squid的传感器置于装有液氦的低温保持器(-269℃)中,通过光纤电缆连接到主机上;③信号处理系

超导量子干涉器件（SQUID）作为磁传感器， 该传感器及其读出电路将探测到的心磁信号转换为电 压信号，经控制电路输出，送入到数据采集卡，供计 算机成像分析及后续数据处理。 注册证号：国食药监械 (进)字2005第2213200号， 产地美国，型号CMI 2409，但临床使用情况并不理 想，注册证过期未延续。 心磁图仪技术审评难点在于国内外无相应的产品 标准、行业标准参考，且心磁图的临床应用及分析方 法尚未形成统一标准。 国内尚无自主研发的同类产品 上市，技术 …
