The QRM-dentalCBCT Phantom (BASIC) is designed to evaluate the imaging performance of conebeam-ct (CBCT) devices in accordance with international guidelines (e.g. dental CBCT, Digital Volume Tomography).

The pahntom offers the possibility to assess image quality metrics in accordance with national and international standards (e.g. DIN IEC 61223-3-5 or DIN IEC 61223-2-6)

The following image quality metrics can be obtained:

  • CT value uniformity
  • CT value accuracy
  • image noise
  • contrast-to-noise ratio
  • spatial resolution (3D MTF, sphere)

An automated evaluation software (ImpactIQ Wizard) is available separately or as a package with the phantom.

Please note:
If using the software, your systems FOV has to completely cover the phantom in height, otherwise a correct automated evaluation is not possible.
Requirement for FOV (Field of View) for the BASIC phantom:
FOVxy > 100 mm; FOVz > 150mm
