The Pro-CT mk II phantom can be used for carrying out acceptance and constancy tests of computed tomography systems according to IEC 61223-3-5 and the AAPM (American Association of Physicists in Medicine) guidelines. This phantom consists of several test modules placed inside a cylindrical container that can be mounted either directly on a holder of the CT table or on an adjustable stand. It allows accurate alignment for measurements on and off the table. Markings on the phantom and leveling aids provide further facilitation of the positioning process.
