Models and Ordering

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

Specifications

• outside cylinder diameter: 178 mm (7’’)
• outside cylinder height: 157 mm
• inside cylinder diameter: 165 mm (6,5’’)
• inside cylinder height: 134 mm
• the phantom is filled with 10 millimolar (mmol) nickel chloride solution containing 0.45% by weight sodium chloride
• 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

• 1 mm wide 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

slice position accuracy

• one set of paired 45° wedges. The distance between the intersection of the wedges is 100 mm

Accessories

• MR-safe carrying bag

Optional accessories

• 2-axis spirit level (09-104)
