QUART DVTap DIN 6868-161
Developed over a period of 2 years in a project involving major dental manufacturers, and released by QUART already in 2007, the DVTap has become a national and international standard solution for CBCT – based on our company’s innovative approach.
The QUART DVTap phantom is designed to be used as a universal tool for 3D imaging equipment including CT applications. The phantom fully complies with DIN 6868-161 for acceptance tests in DVT/CBCT.
In conjunction with a specially developed software (QUART DVTtec), quick and comprehensive CBCT IQ tests can be performed.
Only one exposure is necessary to create a 3D data set containing all required parameters to evaluate CBCT image quality. Automated evaluation is performed with the unique QUART DVTtec software.
The phantom can be used for field sizes from 4x4cm to large fields-of-view (FOV). A universal holder or customized phantom holders are available for easy and reproducible positioning.
