Patent ID: 8626266

Claim:
A method for triggering a magnetic resonance imaging system, comprising: capturing a noisy electrical signal, via at least one main lead, including a biologically generated electrical signal that causes movement in a moving body part of a living being, and noise; capturing, via at least one magnetic resonance noise lead, a noise reference signal indicative of magnetic resonance electromagnetic noise ambient to the at least one main lead; receiving, by a receiving device, the captured noisy electrical signal and the noise reference signal; canceling, by a processing device, the noise reference signal from the captured electrical signal to obtain a processed electrical signal indicative of the biologically generated electrical signal that causes movement in the moving body part of the living being using an adaptive canceling noise filter; detecting, by a processing device, a characteristic of the processed electrical signal indicative of the biologically generated electrical signal that causes movement in the moving body part of the living being to obtain a trigger signal; and transmitting, by a transmitting device, the trigger signal to cause the magnetic resonance imaging system to capture at least one image including the moving body part of a living being.
