碩士 / 國立臺灣大學 / 物理學研究所 / 92 / After the cardiac magnetic field measured by SQUID, One usually wants to locate the sources from the data of the heart activity. To understand this problem we developed the dipole model to locate the main current sources. We proposed that current dipoles generating the cardiac magnetic field are time and space dependent, i.e. the magnitude and the direction of dipoles are changing with time. Then, we used the calculated magnetic field from the dipoles model to fit the measured data. The results of current contours and the time and space variation of the current dipoles are derived from the simulation. In this work, two or more current dipoles for magnetocardiograms are presented and discussed.
