abstract = {Electrocardiogram (ECG) is required during Magnetic Resonance
(MR) examination, for the monitoring of patients under
anaesthesia or with heart diseases and for synchronizing image
acquisition with heart activity (triggering). Accurate and
fast QRS detection is therefore desirable, but this task is
complicated by artefacts related to the complex MR environment
(high magnetic eld, radio-frequency pulses and fast switching
magnetic gradients). Specic signal processing has been
proposed, whether using specic MR QRS detectors or ECG
denoising methods. Most state-ofthe-art techniques use a
connection to the MR system for achieving their task, which
is a major drawback since the access to the MR system is often
restricted. This paper introduces a new method for on-line ECG
signal enhancement, called ICARE, which takes advantage of
using multi-lead ECG and does not require any connnection to the
MR system. It is based on Independent Component Analysis (ICA)
and applied in real time. This algorithm yields accurate QRS
detection for efficient triggering.}
