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.

Features and Benefits

• 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)
• It contains markings for easy positioning in the dental unit.
• Made of PMMA (1.19 g/cm³)
• Containing 15 mm rods made of PTFE, poliamid, PE-300, air and water emulating epoxy embedded PMMA - pixel intensity / HU values samples
• 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
• 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
• 4 Air rods, 3 mm in diameter, placed in vertices of the 30 mm square
• Two aluminium wire ramps
• Accessories:
  • Test stand with spirit level for accurate placing of the phantom in the test position
  • Convenient, portable case for storing and transporting the phantom
• 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.
