Pro-MRI - Versatile Phantom for QC according to ACR, AAPM and IPEM Guidelines


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.


It can be used to measure:

  • Geometric Distortion
  • Spatial Resolution
  • Slice thickness and position
  • Interslice Gap
  • T1 and T2 values
  • Estimate of Image Bandwidth
  • Low Contrast Detectability
  • Image Uniformity
  • Signal-to-Noise Ratio (SNR)
  • Physical and Electronic Slice Offset
  • Point of reference


Technical data (can be modified to customer specifications):

  • Outside cylinder diameter: 220mm
  • Outside cylinder height: 150mm
  • Inside cylinder diameter: 204mm
  • Inside cylinder height: 130mm
  • Filled with 10 mmol nickel chloride solution containing sodium chloride 45 mmol
  • T1 and T2 samples vials
    • 6 cylindrical vials Ø19 x 41mm 
    • Refillable from outside
    • By default filled with 20 mmol nickel chloride and 15 mmol sodium chloride solution
  • 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
  • Slice thickness insert:
    • 180x46x10mm PMMA plate
    • 1mm wide and 5mm deep counter-descending slits on both sides
    • Slits form two ramps descending at a 1:10  
  • Geometric distortion insert:
    • 10 x 10 array of squares 
    • 148mm on a side
    • 10mm thick
  • Low contrast insert:
    • 4 polycarbonate discs 0.05, 0.1, 0.15 and 0.2mm in thickness
    • Partial volume contribution of this sheets and filling solution produce contrasts: 1.4, 2.5, 3.6 and 5.1%
    • Each disc contains 12 groups of 3 holes arranged in spokes 
    • Each spoke has the same diameter
    • Diameters range from 7.0 to 1.5mm (0.5mm step)
  • Four sets of paired 450 wedges are located on both sides of the phantom. Lower pairs are 30x30mm  and upper are 40x40mm. Distance between intersection points of lover and upper pairs is 90mm
  • Optional heavy duty carrying case
