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 customised phantom holders are available for easy and reproducible positioning.
