When used with Pro-CT Dose the phantom can be used to do the following tests:

• Geometric distortion

• CT number (HU) measurement

• Noise / uniformity

• Artefacts

• MTF

• Spatial resolution

• Contrast resolution

• Low contrast resolution

• Slice profile

• Alignment

• Linearity

• Beamwidth

Main module:

• Diameter: 160 mm

• Thickness: 30 mm

• 9 recesses for test inserts allow customized placement of test objects in space

• Markings for easy and accurate positioning in the CT scanner

• Set of holes on a given depth for testing geometry, distortions and slice position

• Screws and extra plugs for mounting the module on any Pro-CT Dose Phantom (04-319)

Standard test inserts:

• 5 contrast resolution inserts containing rods made from different materials: LDPE, PTFE, POM-C, air, plastic water equivalent. Diame ters of rods in each insert are: 2, 4, 6, 8, 10, 12, 14 mm

• High contrast resolution inserts containing 11 aluminium test elements for spatial resolution evaluation from 1 to 11 LP/cm

• 2 geometry modules containing two pairs of aluminium wire ramps whose slope angle tangent is equal to 0.5

• Linear Spread Function (LSF) insert - PTFE / PMMA interface

• Point Spread Function (PSF) insert - 0.25 mm tungsten steel wire in air

optional inserts (04-404):

• 3 low contrast inserts containing rods with a diameter: 2, 4, 5, 6, 8, 10, 12, 14 mm. The contrast difference between the rods and the surrounding material are 0.3, 0.6 and 1%

• 3 high contrast resolution inserts containing 19 aluminium test elements for spatial resolution evaluation from 12 to 30 LP/cm
