Pro-Dent CT mk II

















The new Pro-Dent CT mk II phantom is a versatile quality control tool of dental Cone-Beam CT, Dental Volume Tomography (DVT)
and other 3D imaging devices according to the Radiation Protection Report no 172 by SEDENTEXCT.
The phantom consists of a main PMMA cylinder that houses modules with different test objects. Thanks to this design, you can
perform tests with devices with a small FOV at different positions in the 160 mm phantom.

Technical data (can be modified to customer specifications):
• diameter: 160 mm
• made of PMMA (1.19 g/cm3)
• total length: 170 mm
• noise / uniformity section:
   –– uniform PMMA part of the phantom
• geometric distortion section:
   –– an array of 2.0 mm diameter, 3.0 mm long holes uniformly pitched at 10.0 mm intervals
• slice geometry section:
   –– 20 mm thick module with two pairs of aluminum ramps and empty rods in vertexes of a square for detailed evaluation of slice
       thickness and geometry and laser position verification
• 5 layer modules section with modules containing
   –– Linear Spread Function (LSF) PTFE / PMMA interface
   –– Point Spread Function (PSF) - 0.25 mm stainless steel wire in air
   –– XY high contrast resolution (aluminum/polymer) - 1.0, 1.7, 2.0, 2.5, 2.8, 4.0, 5.0 LP/mm
   –– Z high contrast resolution (aluminum/polymer) - 1.0, 1.7, 2.0, 2.5, 2.8, 4.0, 5.0 LP/mm
   –– 6 low-contrast groups of 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 mm rods made of: aluminum, PTFE, POM-C (delrin), PE-300, air and water
       emulating epoxy; background made of PMMA
   –– 10 mm rods made of aluminum, PTFE, POM-C (delrin), PE-300, air and water emulating epoxy suspended in PMMA - pixel
       intensity / HU values samples
   –– stacked 20 mm diameter contrast-to-noise discs made of aluminum, PTFE, POM-C (delrin), PE-300 and air suspended in
       PMMA
   –– three 5.0 mm diameter titanium rods embedded in PMMA - beam hardening artefacts
• positioning aids on the outside surface of the phantom
• test stand with spirit level for accurate placing of the phantom in the test position
• folding base for test stand positioning on the X-ray unit¡¯s chair
• convenient, portable case for storing and transporting the phantom
• optional additional homogeneity disc Product features:
• Complies with:
   –– Radiation Protection no 172 report by the SEDENTEXCT
   –– IEC 61223-3-4 and IEC 61223-3-5
• CE certified
• the Manual provides detailed guidelines for carrying out each test, results assessment and registration
