Dental Conebeam CT QA Phantom - EXPERT

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

 

The QRM-dentalCBCT Phantom (EXPERT) is designed to evaluate the imaging performance of conebeam-ct (CBCT) devices according to 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)
• spatial resolution (visual, hole pattern)
• artifact behavior metal/bone/soft tissue

5 defined sections

Section I	4 Inserts in water: air, -3% contrast,  +3% contrast and bone arranged  concentrically
Section II	centrally placed high attenuating sphere
Section III	homogenious water equivalent slice
Section IV	acrylic resolution pattern
Section V	Ti rods and tissue equiv. inserts

DIN 6868-161 DVT / Dental-Conebeam-CT Phantom

Perform acceptance and constancy tests in accordance with DIN 6868-161 and other international guidelines.

 

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).

Specifications

Phantom diameter:	160 mm
Phantom height:	150 mm
Body:	PMMA
Design:	Al, D = 12 mm
Inserts:	4 slabs of different thicknesses: 1 main slab with PVC test insert (20 mm) 1 plane slab (fixed to main disk) (20 mm) 2 scatter slabs (50 & 60 mm)

 

ImpactIQ-Wizard - a software tool to quantitatively asses image quality in x-ray CT and CBCT.

ImpactIQ Wizard is a software tool allowing for fast and quantitative assessment of image quality in x-ray computed tomography (CT) for both arbitrary scanners and protocols.

 

ImpactIQ Wizard is a software tool allowing fast and quantitative assessment of image quality in X-ray computed tomography.

The software can be installed on any WindowsTM based computer system. Load a specific dicom image set - and only a few clicks are required to receive a printable report with all necessary image quality parameters. The report can be exported easily as pdf.

ImpactIQ Wizard is available for several specific phantoms, e.g.:

• DVT-161 phantom in accordance with DIN 6868-161
• dentalCBCT QA Phantom (BASIC)
• dentalCBCT QA Phantom (EXPERT)
• Breast-CT Phantom
