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.
