This phantom simulates a contrast medium-enhanced abdomen in portal venous phase. It covers the eleventh thoracic vertebra to the fourth lumbar vertebra (partially included). The phantom has 42 spherical liver lesions with 8 and 12 mm diameters and lesion contrasts of 10, 20, 30 and 40 HU to the surrounding liver.

The phantom can be used in CT (including CBCT) to evaluate and optimize imaging performance and postprocessing applications, including AI-enabled applications. It is also suited for training purposes. The phantom provides a detailed and realistic simulation of soft and bone tissue. Air voids are filled with a cellulose-polymer composite of approx. -160 HU.
