Patent ID: 8380285

Claim:
A method for triggering a measurement of a magnetic resonance device, comprising: detecting a first electrocardiogram signal and a second electrocardiogram signal of a patient via a first channel and a second channel of an ECG respectively; processing the first electrocardiogram signal in a first processing branch of a triggering device by: feeding the first electrocardiogram signal to a low pass filter, feeding the filtered signal to a first derived value sum generator of the triggering device for generating a first output signal, and comparing the first output signal in a first comparator of the triggering device with a threshold value supplied by a threshold value creator for generating a first comparison result of the first electrocardiogram signal; processing the first electrocardiogram signal in a second processing branch of the triggering device by: feeding the first electrocardiogram signal to a second derived value sum generator of the triggering device for generating a second output signal, and comparing the second output signal in a second comparator of the triggering device with an upper and a lower threshold value for generating a second comparison result of the first electrocardiogram signal; repeatly processing the second electrocardiogram signal in the first processing branch and the second processing branch of the triggering device for generating a first and a second comparison results of the second electrocardiogram signal; evaluating the first and the second comparison results of the first electrocardiogram signal and the first and the second comparison results of the second electrocardiogram signal in a weighted logic circuit; and triggering the measurement of the magnetic resonance device by the triggering device based on the evaluation, wherein the threshold value is determined in a learning phase during which none or a negligible interference occur with the detection of the electrocardiograph signals.
