Catheter Calibraon
You perform catheter calibraon by tracing the centerline of a catheter in the image.
You can perform catheter calibraon on either a straight catheter segment or a curved segment, but
you should always use a non-tapered segment. Using a tapered segment for calibraon will result in
incorrect measurement results.
