| Outline of Final Research Achievements |
The ultimate goal of the research is to elucidate the electrical activity in the heart and to develop a diagnostic system for early detection and high-precision diagnosis of heart disease.
Therefore, in this study, we aimed to estimate the electrical activity of the heart and establish a high-precision diagnostic technique by applying the spatial filter method to the magnetocardiogram. We performed an estimation method using multiple measurement surfaces, a consideration to measurement position deviation, and a simulation using a heart model.
As a result, the accuracy of signal source estimation could be improved by multi-sided measurement considering the measurement position deviation.
