Automated procedure for the identification of s ̂ k,ECG . A template matching algorithm was employed for the identification of s ̂ k,ECG . The demixing matrix W obtained from the ECG signals acquired inside the MR scanner (x k ) was applied to the ECG signals acquired outside the MR scanner (xk,out). A QRS template was generated from each IC. s ̂ k,ECG was identified by cross-correlating each QRS template with the corresponding IC in s ̂ k .
