Component selection method of noise rejection based on Independent Component Analysis for MCGs

摘要

In recent years, a magnetocardiogram (MCG) measurement which can detect heart disease early has become important in clinical research. However, it is difficult to know the exact heart activity without noise rejection because MCGs are extremely small compared with the environmental magnetic noise. The most effective noise rejection method is that of using a magnetically shielded room (MSR). But, the MSR has problems on cost and weight. Then, MCG measurement without the MSR is desired.
