Fusion of 3D MRI-derived surfaces with radiocontrast ventriculograms. End-diastolic short-axis SSFP images from apex to base are segmented to define left ventricular endocardial (red), left ventricular epicardial (blue), and right ventricular endocardial (yellow) contours (A). Three-dimensional surfaces are generated from these contours as described in the text and overlaid on the live x-ray display during ventriculography (B) (The asterisk denotes the external fiducial marker) acquired in anteroposterior (AP) (C) and left anterior oblique (LAO) 45° (D) projections.
