QUART DVTkp DIN 6868-15 CBCT Constancy Test Phantom

QUART DVTkp DIN 6868-15 CBCT Constancy Test Phantom Detailed Introduction:

QUART DVTkp DIN 6868-15 CBCT Constancy Test Phantom

The QUART DVTkp 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.

Contrary to DVTap used for acceptance tests, the DVTkp combined with DVTpro is designed for straight forward application in CBCT routine or constancy tests.

Only one exposure is required to create 3D data set containing all required parameters to evaluate image quality. Automated image quality evaluation is performed through the unique QUART QA/QC software.

The DVTkp phantom can be applied for field sizes from 4x4cm to large fields-of-view (FOV). Customised holders for a variety of CBCT systems are available.
