Pro-ct mk ii ct performance module:
Low contrast module
• diameter: 200 mm• thickness 30 mm
• made of pmma
• contains three groups of low contrast objects: each group has a bar of the same density, with an altitude of 20 mm and a diameter range of 1 to 15 mm. The contrast between group and surrounding material is 0. 3, 0. 6 and 1%
• an optional subslice target has a nominal 1. 0% contrast and z axis length of 3, 5 and 7 mm. For each length there are objects with diameters of 2, 3, 5, 7 and 9 mm (04-411)
Light-linear modules
• diameter: 200 mm• thickness: 30 mm
• contains 9 rod-like sensor samples (25 mm diameter): ptfe, ldpe, pom-c, abs, pa-6, pet, air, plastic water equivalent and pmma – module subject
Geometric module
• diameter: 200 mm• thickness: 30 mm
• contains two pairs of steel silks with an arctic angle equal to 0. 5
• the middle of the slope intersects with the same plane, allowing a very precise assessment of the location of the slice
• includes four ø5 mm poles and four ø3 mm poles, located at the top of the octagon near the outside of the model to assess symmetry and circle geometry
• nine spherical bodies can be selected to assess the image of the scanner's protometric spherical volume in diameter: 1. 0, 2. 0, 3. 0, 4. 0, 5. 0, 6. 0, 7. 0, 8. 0 and 9. 0 mm (04-413)
