Figure 3From: Improved R-wave detection for enhanced cardiac Gating using an MRI-compatible 12-lead ECG and multi-channel analysis(a-d) 20-sec breath-held ECGs obtained at 1.5T (a,b) and 3T (c,d) MRIs for AF, PVC and exercising athlete subjects. R designates detected R-wave peaks using 3D-QRS. (e) V1-V6 traces of the AF patient at 3T. All R peaks (dotted lines) are correctly identified (a-e).Back to article page
