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)

Noise / uniformity module

• 20 mm thick

‍

Linearity module

• containing 15 mm rods made of PTFE, polyamide, LDPE, air and water emulating epoxy embedded PMMA - pixel intensity / HU values samples

‍

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

• 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

• 4 air rods, 3 mm in diameter, placed in vertices of the 30 mm square
• two aluminium wire ramps

‍

Accessories:
