Pro-Dent CT


Price: Call JRT for Pricing


The Pro-Dent CT phantom is an 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.

The size of the phantom corresponds to a human skull (15 cm 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 a limited field of visualization. Also, quality is evaluated in the clinically essential region.

With the Pro-Dent CT you can do the following tests:
  • Image geometry
  • Pixel (matrix) size
  • Artifacts, noise
  • Homogeneity
  • Linearity
  • Contrast
  • High-contrast resolution
  • Low-contrast resolution (contrast sensitivity)
Technical data (can be modified to customer specifications):
  • Main test module dimensions: ø 150mm, 40mm thickness, containing:
    • Four sensitometric samples ø 20mm made of: PTFE (teflon), POM C (polyoxymethylene), PE 300 (polyethylene) and air
    • Four o 3mm rods, filled with air, placed in vertexes of a square (side length 50mm)
    • Seven low contrast rods of a different diameter: 2, 3, 4, 6, 8, 10, 12mm, filled with a substance whose density is 3% different from the body of the module
    • Seven high contrast patterns for line pair resolution evaluation, from 10 to 16 LP/cm
    • Three beads: ø 0.2, 0.25, 0.3mm
  • Optional ø 150mm, 20mm thick geometry modue with two pairs of aluminum ramps, empty rods in vertexes of a square and positioning markers for detailed evaluation of image geometry and laser position verification
  • Additional smaller homogenous cylinder filled with a substance with a density similar to water: ø 150mm, 30mm thickness
  • Additional larger homogenous cylinder filled with a substance with a density similar to water: ø 150mm, 130mm thickness
  • Test stand with a table for placing the phantom in the test position
  • Folding base for test stand positioning on the X-ray unit’s chair
  • Convenient, portable case for storing and transporting the phantom
  • Complies with IEC 61223-3-4, IEC 61223-3-5; CE certified
