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.
Technical Data
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
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
(can be modified to customer specifications)
