QUART DVT_AP CBCT模体，QUART DVT_AP锥形束CT模体英文介绍: QUART DVT_AP DIN 6868-161 CBCT Image Quality Test Phantom
The QUART DVT_AP 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 CBCT applications.
In conjunction with a specially developed software (QUART DVT_TEC), quick and comprehensive CT IQ tests can be perbbbbed.
Only one exposure required to create 3D data set containing all required bbbbbeters to bbbbuate image quality. Automated bbbbuation through unique QUART QA/QC software.Phantom can be applied for field sizes from 4x4cm to large fields-of-view (FOV). A universal holder or customised phantom holders available for easy and reproducible bbbbbbbbing.
