Dental CBCT QA Phantom, Expert

For testing the imaging performance of dental cone-beam CT systems

For testing the imaging performance of dental cone-beam CT systems
A compact easy-to-use phantom for acceptance and constancy tests
Allows 3D MTF measurements

Measure imaging performance of dental Cone-Beam CT equipment. Perform acceptance and constancy tests with a compact easy-to-use phantom.

The Dental CBCT QA Phantom, Expert is designed to evaluate the imaging performance of Cone-Beam CTs, e.g., in dental application or for Digital Volume Tomography (DVT) systems.

The following image quality parameters can be determined according to DIN IEC 61223-3-5 or DIN IEC 61223-2-6:
- CT value uniformity
- CT value accuracy
- Image noise
- Contrast-to-noise ratio (CNR)
- Spatial resolution (3D MTF, sphere).
- Spatial resolution (visual, hole pattern)
- Artifact behavior of metal, bone and soft tissue.
