QUART DVT_KP

DIN 6868-15 CBCT Constancy Test Phantom

The QUART DVT_KP phantom is designed to be used for routine QA/QC within the full range of Cone Beam CT (CBCT), Dental Volume Tomography (DVT) and 3D imaging equipment.

The phantom fully complies with DIN 6868-15 for CBCT constancy tests.

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). Customised holders for a variety of CBCT systems available.
