The Pro-CT MINI phantom is a compact CT image quality testing solution. When connected with Pro-CT Dose it may be used for carrying out acceptance and constancy tests of computed tomography systems according to IEC 61223-3-5 and the AAPM (American Association of Physicists in Medicine) guidelines.

This phantom consists of a module 16cm in diameter with positioning aids and recesses for test modules.

When used Pro-CT Dose the phantom can be used to do the following tests:

  • Geometric distortion
  • CT number (HU) measurement
  • Noise / Uniformity
  • Artefacts
  • MTF
  • Spatial resolution
  • Contrast resolution
  • Low contrast resolution)
  • Slice profile
  • Alignment
  • Linearity
  • Beamwidth

Technical data (can be modified to customer specifications):

  • main module:
    - diameter: 160mm
    - thickness: 30mm
    - 9 recesses for test inserts allow the customized placement of test objects in space
    - markings for easy and accurate positioning in the CT scanner
    - set of holes on a given depth for testing geometry, distortions and slice position.
    - screws and extra plugs for mounting the module on any Pro-CT Dose phantom
  • standard test inserts
    - 5 contrast resolution inserts containing rods made from different materials: LDPE, PTFE, POM-C, air, plastic water equivalent. Diameters of rods in each insert are: 2, 4, 6, 8, 10, 12, 14mm
    - 4 high contrast resolution inserts containing 11 aluminium test elements for spatial resolution evaluation from 1 to 11 LP/cm
    - 2 geometry modules containing two pairs of aluminium wire ramps whose slope angle tangent is equal to 0.5.
    - Linear Spread Function (LSF) insert - PTFE / PMMA interface
    - Point Spread Function (PSF) insert - 0.25 mm tungsten steel wire in air
  • optional inserts (04-404)
    - 3 low contrast inserts containing rods with a diameter: 2, 4, 6, 8, 10, 12, 14mm. The contrast difference between the rods and the surrounding material are 0.3, 0.6 and 1%.
    - 3 high contrast resolution inserts containing 19 aluminium test elements for spatial resolution evaluation from 12 to 30 LP/cm
