Computed Tomography

Phantom for CTDI measurements, consisting of head (diameter 16cm) and body (diameter 32cm in combination with head-phantom) with holes for ionisation chamber.

For water value, noise, homogenety and slice thickness examinations at spiral CT scanners; can be used in combination with the scanner manufacturer's specific constancy test phantom.

Designed to evaluate the spatial resolution capabilities of a CT scanner in x-y-plane as well as in z-x-plane. The phantom is built of two orthogonal PMMA plates with 12 series of bore holes which represent spatial frequencies between 1.25 lp/cm and 12.5 lp/cm.

Designed to evaluate the slice sensitivity profiles (SSP) of a CT scanner's spiral / helical scan modes. The phantom contains a 25 micron metal foil embedded in a cylinder of uniform tissue equivalent plastic material.

For use with anthropomorphic thorax phantoms or easy cubes (Adapter neccessary).

For evaluation of the maximum obtainable performance potential of axial and spiral CT scanners

For evaluation of the maximum obtainable performance potential of multi-slice CT scanners with enhanced sensitometry samples for radiation therapy planning.
