Philips Azurion - 8.14.1 Creating a Distance Measurement; 8.14.2 Creating a Polyline Measurement

CAUTION
If you use aut
o calibraon for measurements or quantave analysis, the region of interest must be
posioned as close to the isocenter as possible during acquision. If the region of interest is not in the
isocenter, the calibraon factor will not be correct and measurements will not be accurate.
If auto calibraon is not available, you should calibrate the series manually. For more informaon, see
Manual Calibraon (page 144).
NOTE If you accept the calibraon factor, measurement values are displayed in millimeters. If you
do not accept the calibraon factor, measurement values are displayed in pixels.
Accuracy
Accuracy of length measurements, when calibrated automacally, is ±5% when the measured object is
in the isocenter and where the length of the object is at least 50 pixels on the monitor.
Accuracy of angle measurements is ±2 degrees.
