摘要：
High resistance non-metallic ECG leads are used to capture biologically generated electrical signals, and include at least one magnetic resonance noise lead to capture a noise reference signal indicative of electromagnetic noise ambient to the leads generated by magnetic resonance imaging (MRI). The noise reference signal is canceled from the captured electrical signal using an adaptive canceling noise filter to obtain a processed electrical signal indicative of the biologically generated electrical signal that causes movement in a patients moving body part, such as the heart. A characteristic of the processing electrical signal indicative of the biologically generated electrical signal that causes the movement is detected to obtain a trigger signal, which is then transmitted to cause the MRI system to capture at least one imagine including the moving body part.
