Micro-CT Low Contrast Phantom

As a useful tool for evaluation of contrast detectability the MicroCT Low Contrast Phantom provides four inserts of two different contrast levels, each in two different dimensions.

The MicroCT Low Contrast Phantom is a cylindrical phantom in which small details (cylindrical inserts) at a specified contrast with respect to the background allow for an estimation of the low-contrast resolution of a Micro-CT scanner. The difference in Hounsfield Units can be as low as -40 HU and -80HU, respectively.
Actual values vary slightly depending on scanner geometry, calibration and tube voltage.

Standard phantoms are scaled down from the diameter of an average human trunk (32 cm) to that of a fat mouse or lean rat (32 mm). Other dimensions as well as inserts with substances other than specified here can be produced upon request.
