QUART DVTap

IAEA-EFOMP-ESTRO CBCT and CT Image Quality Test Phantom

The QUART DVTap phantom is designed to be used as a universal tool for 3D imaging equipment including CT applications.

The phantom (combined with QUART's CTtec software) has been endorsed by IAEA, EFOMP and ESTRO as a comprehensive solution for time-efficient CT and CBCT QA procedures.

Only one exposure required to create 3D data set containing all required parameters to evaluate image quality. Automated evaluation through unique QUART QA/QC software.Phantom can be applied for field sizes from 4x4cm to large fields-of-view (FOV). A universal holder or customised phantom holders available for easy and reproducible positioning.
