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
Technical data:
- 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
Product included:
- hard-sided carrying case (MR unsafe) (09-102)
- optional 2-axis spirit level (09-104-1)
