The phantom provides a realistic lation of a dog with no contrast agent. Bones and soft tissue are displayed authentically with realistic CT values for all tissues at 120 kVp tube voltage in the CT. Air spaces are filled with a cellulose polymer composite with about -80 Hounsfield units. If the phantom is to be used primarily with other tube voltages (e.g. 100 kVp), the calibration of the CT values can be adjusted accordingly if required. The phantom also provides realistic tissue contrasts in X-ray imaging.
