Pro-CT AAPM - Pro-Project - 04-501
The Pro-CT AAPM phantom may be used for carrying out tests of computed tomography systems according to Report no. 1 of the AAPM (American Association of Physicists in Medicine).
Technical data (can be modified to customer specifications):
- PMMA water tank:
- Inside cylinder diameter: 214mm
- Outside cylinder diameter: 220mm
- Lid has quick disconnect valves for ease of filling and draining
- Aluminum alignment pin (6.3mm Ø x 76mm) or a polystyrene TLD insert (for dose measurements) can be attached to the lid
- Low contrast section:
- Placed at one end of the water tank
- 12 fillable cavities 40mm deep
- Two pieces of each cavity with diameters: 25.4, 19.0, 12.7, 9.5, 6.4 and 3.2 mm
- Spaced twice their diameter apart from the centerline
- Cavities can be easily filled from the outside with dextrose or sodium chloride solutions of various concentrations
- Bone insert:
- PTFE annulus
- Wall thickness 6.4mm, 70mm long
- Fits over all inserts to harden the beam
- CT number linearity insert:
- Five 25mm rods
- Material: polyethylene, PMMA (acrylic), polycarbonate, polystyrene and nylon
- Density values (g/cm3): 0.95, 1.19, 1.20, 1.05 and 1.1 respectively
- Resolution insert:
- Eight sets / rows of air thru holes (five holes per set)
- Diameters of holes: 1.75, 1.5, 1.25, 1.00, 0.75, 0.61, 0.50 and 0.40 mm
- Distance between each hole is equal to the hole diameter
- Distance between rows 5mm
- 0.2mm stainless steel wire positioned longitudinally for calculation of line-spread function
- Slick thickness insert:
- Three aluminum strips, 0.5mm thick and 25mm wide angled at 45°, positioned at the centre and aligned vertically
- Geometry insert (optional):
- Contains two pairs of aluminium wire ramps whose slope angle tangent is equal to 0.5
- Middles of ramps intersect on the same plane allowing for very precise evaluation of the slice location
- Contains two sets of four PMMA rods (Ø 10mm) placed in vertexes of two squares (sides 100mm long)
- Triple low contrast insert (optional):
- Contains three groups of low-contrast objects. In each group, there are rods of the same density, 20mm in height and with a diameter ranging from 2 to 15mm. Density difference between groups and
surrounding material is exactly 0.3%, 0.6% & 1.0%
- Made of PMMA
- Filling tubes
- Heavy duty carrying case (optional)
Product features:
- Complies with:
- Report no. 1 of the AAPM (American Association of Physicists in Medicine)
- IEC 61223-3-5
- IEC 61223-2-6
- CE certified
- The manual provides detailed guidelines for carrying out each test, results assessment and registration
