The QRM-DVT-161 Phantom is designed to perform acceptance and constancy testing in accordance to DIN 6868-161 and QS-RL. It provides the capability to evaluate imaging performance of dental CBCT equipment (DVT, Digital Volume Tomography). In accordance with DIN 6868-161 the following image quality metrics can be obtained:

  • spatial distorsion in reconstructed volume
  • in-plane resolution (MTF)
  • acceptance indicator
  • uniformity indicator

The phantom consists of 4 sections. The main section (20 mm height) contains the PVC test insert to evaluate spatial resolution, contrast to noise ratio and the acceptance indicator. A second section (plain, 20 mm height) is used to measure noise and homogeneity. For the ease of use the two sections are fixed together. In addition two optional scatter sections are in the package (50 and 60mm height).

The following image quality metrics can be obtained:

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