A possible way to solve problems in CT densitometry.
The common computed tomography (CT) densitometric scale expressed in Hounsfield units does not possess sufficient representativity. A standard scale is needed to solve problems in CT densitometry. A new scale based on a special phantom with different solutions of calcium chloride permits the elimination of shortcomings of the common scale. Indications for testing CT scanners with the help of the phantom are offered.
