Pro-MRI ACR Medium - Diagnomatic - 09-301

Pro-MRI ACR Medium - 09-301 - Diagnomatic

Pro-MRI ACR Medium - 09-301 - Diagnomatic - phantom and case

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
outside cylinder height: 157 mm
inside cylinder diameter: 165 mm
inside cylinder height: 134 mm
filled with 10 mmol nickel chloride solution containing sodium chloride 75 mmol
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:

158 x 52 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:

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
four sets of paired 45° wedges are located on both sides of the phantom. The lower pairs are 20 x 20 mm, and the upper ones are 30 x 30 mm.
heavy duty carrying case (09-102) (Included)
optional detachable 3-axis spirit level (09-104) (Not Included)
