       Pro-MRI - ACR accredited Medium MRI phantom.       
Pro-Project! ACR accredited Medium MRI phantom for comprehensive evaluation of critical imaging parameters of magnetic resonance imaging (MRI) in a time efficient manner. The phantom can be used for the measurement of absolute values for calibration purposes. However, its design is optimized for time efficient daily quality assurance too. 
Large version coming soon!

It can be used to measure:
  • geometric distortion
  • spatial resolution
  • slice thickness and position
  • interslice Gap
  • image bandwidth
  • low contrast detectability
  • image uniformity
  • signal-to-noise ratio (SNR)
  • physical and electronic slice offset
  • point of reference
  • bandwidth: water-fat shift

  • Technical data:
  • outside cylinder diameter: 178 mm
  • outside cylinder height: 157 mm
  • inside cylinder diameter: 165 mm
  • inside cylinder height: 134 mm
  • filled with 10 mmol nickel chloride solution containing sodium chloride 75 mmol
  • the outside of each phantom has the words “NOSE” and “CHIN” etched into it as an aid to orienting the phantom for scanning, as if it were a head

  • Resolution insert:
  • four matrices of holes, diameters: 0.8, 0.9, 1.0 and 1.1 mm
  • spaces between the holes are equal to hole diameters
  • two small containers with water and fat for water-fat shift evaluation





  • Slice thickness insert:
  • 158 x 52 x 10 mm PMMA plate
  • 1 mm wide and 5 mm deep counter-descending slits on both sides
  • slits form two ramps descending at 1:10

  • Geometric distortion insert:
  • 3x3 holes array, 40 mm spacing
  • 2 mm diameter
  • 120 mm on a side
  • 10 mm thick

  • Low contrast insert:
  • partial volume contribution of these sheets and filling solution produce contrasts: 1.4, 2.5, 3.6 and 5.1%
  • each disc contains 10 groups of 3 holes arranged in spokes
  • each spoke has the same diameter
  • diameters range from 7.0 to 1.5 mm‍
  • four sets of paired 45° wedges are located on both sides of the phantom. The lower pairs are 20 x 20 mm, and the upper ones are 30 x 30 mm.
  • heavy duty carrying case (09-102)
  • optional detachable 3-axis spirit level (09-104)

  • Product features:
    ACR Accredited - complies with:- ACR MRI Accreditation Program- IPEM Report 80 “Quality Control in MRI”, 1998- AAPM Rep. 28 “Quality Assurance methods & phantoms for MRI”, 1990- AAPM Rep. 34 - “Acceptance testing of MRI systems”, 1992- AAPM Rep. 100 - “Acceptance & Quality Assurance procedures for MRI facilities”, 2010 - CE certified
