Dental CBCT QA Phantom

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 Phantoms (basic or expert versions available) are 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).

The expert version additionally allows the determination of the spatial resolution (visual, hole pattern) and checks the artifact behavior of metal, bone and soft tissue.
