Calibrating The Measurement Feature - CAE CathLabVR Simulator User Manual

Calibrating the Measurement Feature

QCA (Quantitative Cine Angiometrics) allows the user to record a Cine Angiogram, pause the Cine and
make detailed measurements from the still image. Prior to any measurements, the user should
calibrate so that measurements are accurate in the chosen angle and zoom magnification.
QCA calibration should be performed prior to obtaining any measurements from a Still cine image. It
is best to select a catheter or tool with a known dimension, (such as the diameter of the guide
catheter), and use this to calibrate the QCA measurement.
To calibrate a measurement:
1. Record a cine image
2. Pause the cine loop to obtain a "still" image
3. Right-click on one side of the catheter and right-click again on the opposite side of the
catheter
A blue line appears, representing the diameter of the catheter.
4. From the Cine feature options, select Calibrate
The QCA dialog box will prompt the user to input the desired measurement, (the known
diameter of the catheter, in millimeters).
5. Once this valued is entered, any new measurements will be correct in the current view
and magnification
Note: If the anatomy is viewed in a new Fluoro angle, or a different Zoom magnification,
the QCA measurements should be re-calibrated in the new view prior to any new
measurements.
