It can be used to measure:

• Geometric distortion

• Spatial resolution

• Slice thickness and position

• Interslice Gap

• T1 and T2 values

• 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: 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

• 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

‍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

• Each spoke has the same diameter

• Diameters range from 7.0 to 1.5 mm (0.5 mm step)

‍Accessories:

• MR-safe carrying bag

‍Optional accessories:

• 2-axis spirit level (09-104)

• 6 removable vials for test samples - replacing the “T1 and T2 sample vials”, includes 6 additional vials (in 12 total) (09-103)
