7.4.8 Volume Calibration
A “phantom bladder” will be needed for calibration. The phantom mimics a human bladder with a
known volume. The phantom should be scanned and the measured volume should be the same as the
phantoms standard volume. If the measured volume is different from phantom’s standard volume,
use the correcting parameter to calibrate the device. The range of its correction is ±40ml.
