QUART SP vario

R+F Image QA Test Phantom

The QUART SP vario test phantom is designed for image QA/QC in film-screen based radiography.

It can also be used for basic resolution tests in digital x-ray imaging modalities using added filtration such as the QUART al25.0.

The phantom is free of planar grid structures, thus clearly revealing disturbing artefacts in the imaging chain.

The QUART SP vario complies with DIN 6868-3 and DIN 6868-4.
