       CIRS MicroMouse CT Phantom.       

Computerized Imaging Reference Systems, Inc! Provides standard of reference for Micro-CT scanner

The CIRS Model 090, MicroMouse Phantom, provides a tool for quantifying calcium and bone density with respect to x-ray attenuation and absorption properties. Hydroxyapatite (HA), the principal constituent of teeth and bones within mammals, is the most appropriate reference for mineral density evaluations. CIRS blends HA in a soft-tissue equivalent, polymer background to provide references which can range in HA loading between 0 mg/cc and 750 mg/cc. Hydroxyapatite grain size and homogeneity of the rods are optimized for use in Micro-CT.

The MicroMouse Phantom contains 11 rods of varying mineral loading and dimension. The rods are embedded in soft tissue equivalent material that is of the size and shape of a small rodent.

The Model 090 can be used to evaluate Micro-CT scanners as you would standard whole body scanners. The targets are suitable for determining contrast detectability and estimating low-contrast resolution.
