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).

Pro-Dent CT MINI Overview

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)

Noise / uniformity module

uniformity module
  • 20 mm thick

Linearity module

linearity module
  • containing 15 mm rods made of PTFE, poliamid, PE-300, air and water emulating epoxy embedded PMMA - pixel intensity / HU values samples

High contrast resolution module

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

Low contrast section

low contrast resolution
  • 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

Slice geometry module

slice geometry
  • 4 air rods, 3 mm in diameter, placed in vertices of the 30 mm square
  • 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

Product features:

  • complies with:
    - 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
