A phantom for evaluating high
contrast materials in Micro-CT.
Materials of highest interest in small-
animal imaging (CaHA and Iodine).
The contrast scale factor allows evaluating the contrast, measured in Hounsfield Units, obtained for a given concentration of a substance,
3
specified in mg/cm . The MicroCT-ContrastScale
phantom provides HA (calcium hydroxyapatite) and iodine samples, i.e. the substances of highest interest in small-animal imaging.
The 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 concentrations other than specified here can be produced upon request.
