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 16 cm 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:

  • Main module:
    • Diameter: 160 mm
    • Thickness: 30 mm
    • 9 recesses for test inserts allow 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. Diame ters of rods in each insert are: 2, 4, 6, 8, 10, 12, 14 mm
    • 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, 5, 6, 8, 10, 12, 14 mm. 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
