摘　　要：研制了用于心磁测量的直流高温量子干涉器,并建立了单通道高温直流超导量子干涉器心磁图仪.根据临床诊断标准,在磁屏蔽室内依次调节无磁床的位置,采集了人体胸前平面5×5正方格子上各点的心磁数据.实验结果表明,健康人与心脏病患者的心脏磁场信号存在明显差异.利用该系统,可为心脏病的临床诊断提供有价值的实验数据.A high temperature superconducting quantum interference device （SQUID） was fabricated for magnetocardiogram （MCG） measurement, and a single-channel dc SQUID magnetocardiograph was developed, According to clinical diagnosis standard, by sequentially adjusting the non-magnetic patient table with 5 cm pitch in x and y directions the magnetic field signals perpendicular to the human chest on a rectangle grid of 5 × 5 over the chest area were recorded in a magnetically shielded room. The significant difference of magnetocardiogram between a healthy heart and the heart with right bundle branch block was observed. A large quantity of magnetocardiogram data for clinical diagnosis analysis were recorded with the system.
