Dental CBCT Phantom

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

OVERVIEW

Compact phantom for acceptance and constancy tests according to DIN / IEC 61223-3-5 and 61223-2-6

The Dental CBCT Phantoms (expert or basic 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
spatial resolution (3D MTF, sphere).

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