  • Method for generating a gating signal for cardiac MRI
    Patent number: 6070097
    Abstract: An MRI system includes a detector system which receives an ECG signal from a patient being scanned and produces a gating signal. The gating signal is produced when a detected peak in the ECG signal meets a set of R-wave criteria which includes a specified positive slope on the leading segment of the detected peak, a minimum duration of the leading segment, specified negative slope on the segment trailing the detected peak and a minimum peak amplitude.
