carrying case

Low contrast

diameter: 200 mm

thickness: 30 mm

made of PMMA

contains three groups of low-contrast objects: in each group, there are rods of the same density, 20 mm in height and with a diameter ranging from 1 to 15 mm. Contrast difference between groups and surrounding material is 0.3, 0.6 and 1%

optional subslice targets having a nominal 1.0% contrast and z-axis lengths of 3, 5, and 7 mm. For each of these lengths, there are objects of 2, 3, 5, 7 and 9 mm in diameter (04-411)

Sensitometry

diameter: 200 mm

thickness: 30 mm

contains 9 sensitometric samples shaped like rods (ø25 mm): PTFE, LDPE, POM-C, ABS, PA-6, PET, air, plastic water equivalent and PMMA – modules body

Geometry

diameter: 200 mm

thickness: 30 mm

contains two pairs of steel wire ramps whose slope angle tangent is equal to 0.5

middles of ramps intersect on the same plane allowing very precise evaluation of the slice location

contains four ø5 mm rods and four ø3 mm rods from the air in the vertices of the regular octagon close to the outer perimeter of the phantom for evaluating symmetry and circular geometry

optional nine spheres to evaluate the scanner’s imaging of subslice spherical volumes, diameters: 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 and 9.0 mm (04-413)

Resolution

diameter: 200 mm

thickness: 30 mm

contains 13 concentrically placed high contrast elements for spatial resolution evaluation from 1 to 13 LP/cm

two tungsten carbide beads ø0.18 mm and ø0.28 mm for MTF and SSP calculation

Linear Spread Function (LSF) PTFE / PMMA interface

Point Spread Function (PSF) - 0.25 mm stainless steel wire in air

optional, additional concentrically placed high contrast elements for spatial resolution evaluation from 14 to 30 LP/cm (04-414)

Homogeneous

diameter: 200 mm

thickness: 35 mm

can be filled with water

Optional module made of Pro-Water water-equivalent (04-421)

diameter: 200 mm

thickness: 35 mm

mimics true water within 1% accuracy

Optional electron density module (04-416)

diameter: 200 mm

thickness: 30 mm

module made of Pro-Water

contains samples of 10 different rod-shaped materials (30 mm diameter) with the known physical and electron density corresponding to the following tissues: lungs (inhale), lungs (exhale), breasts (50/50), dense bone, bone marrow, liver, muscles, adipose tissue; additionally, a sample with water and a optional titanium rod
