Visual comparison of contouring approaches in ScanIP and Osirix.
A. Contour representation in ScanIP. Pixels within the endocardium are selected (based on thresholding or manual selection), to be exported in a binary image format. B. Contour representation in OsiriX. Contours markers are placed at points around the endocardium, and a spline curve is interpolated between these points.
