8.14.6 Manual Calibraon
To ensure accurate measurements, the measurement funcon must be calibrated.
You can perform manual calibraon using one of the following methods:
• Catheter
• Distance
• Sphere
NOTE When performing manual calibraon on biplane images, you must perform calibraon on
frontal image and the lateral image separately.
Catheter Calibr
a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.
1 In the Calibraon and Measurements task panel, click Manual Calibraon to display the
Calibraon dialog box.
2 In the Cal. Method list, select Catheter.
