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.
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
Optional 6 removable vials for test samples - replacing the “T1 and T2 sample vials”, includes 6 additional vials (in 12 total) (09-103)
Optional hard-sided carrying case (MR unsafe) (09-102)
Optional detachable 3-axis spirit level (09-104)
T1 and T2 sample vials:
6 cylindrical vials Ø19 x 41 mm
Refillable from outside
Filled with different configurations of nickel chloride and sodium chloride solution, precise information to be found in the manual
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
10 mm thick
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

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.
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
