Pro-Dent CT MINI


Pro-Dent CT MINI phantom is a versatile quality control tool of dental Cone-Beam CT, Dental Volume Tomography (DVT). and other 3D imaging devices with even the smallest FOV (Field Of View).

The phantom consists of a main PMMA cylinder that houses modules with different test objects.

It allows performing most important imaging quality tests such as:

  • image geometry
  • slice geometry
  • pixel (matrix) size
  • artefacts, noise
  • homogeneity
  • linearity
  • contrast
  • high-contrast resolution
  • low-contrast resolution (contrast sensitivity)

Technical data (can be modified to customer specifications):

Main cylinder

  • contains markings for easy positioning in the dental unit
  • geometric distortion section - an array of 2.0 mm diameter, 3.0 mm long holes uniformly pitched at 10.0 mm intervals
  • diameter: 110 mm
  • length: 130 mm
  • made of PMMA (1.19 g/cm³)
An empty transparent acrylic container with an unscrewed lid.

Noise / uniformity module

  • 20 mm thick
A sanded acrylic disc.

Linearity module

  • containing 15 mm rods made of PTFE, polyamide, LDPE, air and water emulating epoxy embedded PMMA - pixel intensity / HU values samples
A polished acrylic disc with 5 round elements arranged in a circle, placed in the center.

High contrast resolution module

  • containing 7 objects for resolution evaluation: 10, 11, 12, 13, 14, 15, 16 LP/cm
  • 0.3 mm bead for Modular Transfer Function (MTF) calculation
A sanded acrylic disc with 6 rectangular elements arranged concentrically in a circle, placed in the centre.

Low contrast section

  • containing rods of a different diameter: 2, 3, 4, 6, 8, 10, 12 mm, filled with a substance whose density is 3% different from the body of the module
Sanded acrylic disc with 7 cylindrical elements of different diameters arranged in a circle, placed in the centre.

Slice geometry module

  • 4 air rods, 3 mm in diameter, placed in vertices of the 30 mm square
  • two aluminium wire ramps
Sanded acrylic disc with 4 holes placed in the middle in vertices of the square and two aluminium wire ramps.


  • test stand with spirit level for accurate placing of the phantom in the test position
  • convenient, portable case for storing and transporting the phantom
