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.

Features and Benefits

• Outside Cylinder Diameter: 220 mm (180 mm)
• Outside Cylinder Height: 150 mm
• Inside Cylinder Diameter: 204 mm (173 mm)
• Inside cylinder height: 130 mm
• Filled with 10 mmol nickel chloride solution containing
• Sodium chloride 75 mmol
• T1 and T2 sample vials
  • 6 cylindrical vials Ø 19 x 41 mm
  • 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
  • Two small containers with water and fat for water-fat shift evaluation
• Slice Thickness Insert
  • 180 x 46 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:
  • 10 x 10 array of squares
  • 148 mm on a side
  • 148 mm on a side
• Low Contrast Insert
  • 4 polycarbonate discs 0.05, 0.1, 0.15 and 0.2 mm in thickness
    
  • Partial volume contribution of these 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 45° wedges are located on both sides of the phantom. The lower pairs are 30 x 30 mm and the upper ones are 40 x 40 mm. The distance between intersection points of the lower and upper pairs is 90 mm.
• Can be used to measure the following:
  • 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
  • Bandwidth: water-fat shift
• Included heavy duty carrying case
• Optional 6 removable vials for test samples - replacing the "T₁ and T₂ sample vials”, includes 6 additional vials (12 total)
