The Pro-Dent CT phantom is innovative solution for quality control of dental tomography systems and other X-ray devices with 3D function. It was developed in cooperation with leading producers of dental tomography units.

Size of the phantom corresponds to a human skull (15cm in diameter) and all test patterns are located in the area matching the maxilla. This allows for a reliable and quick testing of x-ray devices, even with limited field of visualization. Also, quality is evaluated in the clinically essential region.

With the Pro-Dent CT you can make following tests:

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

Technical data:

• main test module dimensions: ø 150mm, 40mm thickness
• contains four sensitometric samples ø 20mm made of: PTFE, nylon, LDPE and air
• contains four rods ø3mm, filled with air, placed in vertexes of a square (side length 50mm)
• contains seven low contrast rods of a different diameter: 2, 3, 4, 6, 8, 10, 12mm, filled with a substance having density 3% different form the body of the module
• contains seven high contrast patterns for line pairs resolution evaluation, from 10 to 16 LP/cm
• contains one ø 0.3mm bead
• additional smaller homogenous cylinder filled with substance having density similar to water: ø 150mm, 30mm thickness
• additional larger homogenous cylinder filled with substance having density similar to water: ø 150mm, 130mm thickness
• test stand with table for placing phantom in the test position (main test module should be placed between the smaller and the larger homogenous cylinder)
