Abstract :
A simple and successful method for cardiac-MRI-gating is proposed. The adaptive interference cancellation filter (AICF) is used with a synthesised reference signal to reduce the gradient artefacts caused by the magnetic resonance (MR). The reference signals of the AICF were a combination of the noisy, three-channel ECG signals. In particular, the proposed method is based on a simple experimental setup and does not require any information from amplifiers of the MRI machine, such as shape, amplitude and rise time.
