Abstract

Abstract

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.
