| Outline of Final Research Achievements |
The purpose of this study is to develop a magnetically shielded roomless magnetocardiogram measurement system enabling early stage diagnosis of heart disease. In order to measure the magnetocardiogram with a high signal noise ratio outside the magnetically shielded room, magnetic noise was removed by hardware and software. The shielding factor by hardware was able to achieve about 27 dB in the ideal state. The shielding factor by software was able to achieve an average of about 33 dB.
The magnetocardiogram waveform actually measured using this system outside the magnetically shielded room was able to realize a high signal noise ratio. Furthermore, it has become possible to create three-dimensional visualization software of the active part of the heart and to capture the activity of the heart three-dimensionally.
