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, (04-319),
  • 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,
    • 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,
  • Carrying case.
