Short CV |
Jaakko A. Malmivuo received the M.Sc. and Ph.D. degrees from Helsinki University of Technology, Finland, in 1971and 1976, respectively. From 1974
to 1976, he was a researcher at Stanford University. In 1976, he was appointed as associate professor and in 1986 professor of bioelectromagnetism at Tampere University of Technology (TUT), Tampere, Fnland. Since 1992, he has been director of the Ragnar Granit Institute at TUT. He has served as a visiting professor at the Technical University of Berlin (West) (1988), Dalhousie University, Halifax, Canada (1989), and Sophia University, Tokyo (1993). He has published over 250 scientific publications and is the coauthor (with R. Plonsey) of Bioelectromagnetism (Oxford Univ. Press, New York, 1995). Dr. Malmivuo was president of the Finnish Society for Medical Physics and Medical Engineering from 1987-1990. He is the founder president of the International Society for Bioelectromagnetism from 1995-2000. He is also editor in chief of the International Journal of Bioelectromagnetism. Dr. Jaakko Malmivuo has lectured on bioelectromagnetism on several international courses in Finland and abroad. |
Title: | Bioelectromagnetism - Relative Merits of Bioelectric and Biomagnetic Measurements. |
Abstract |
The most important issue in bioelectromagnetism is: Do the biomagnetic measurements bring new information from the source in addition to the bioelectric ones? Are the biomagnetic measurements independent on the bioelectric ones or are they only a different modality of the same
phenomenon: detection of the bioelectric activation of the cells? This issue is discussed with applications on cardiac and brain studies. The clinical studies show that the vector magnetocardiography, VMCG has similar diagnostic performance as the vector electrocardiography, VECG. We have shown that when combining these two methods to the vector electromagnetocardiography, VEMCG, the number of incorrectly diagnosed patients may be decreased to one half. This is a statistically significant improvement in the diagnostic performance. This indicates that VMCG has clinical value. We have also proven that according to the Helmholtz's theorem, the correct lead fields of electric and magnetic measurements are fully independent. However, the bioelectric and biomagnetic signals are only partially independent. |
