This phantom is designed according to ICRU 87 report and AAPM TG-200 specifications. The phantom comprises high-density polyethylene (mass density of 0.97 g/cm3) and is 300 mm in diameter. The total length of the phantom is 600 mm. This allows to capture the majority of the scattered radiation and gives more accurate results than standard PMMA cylinders – 150mm long, 320mm in diameter. Due to the large mass of the phantom, it is manufactured in three separate sections. In order to keep these sections aligned, alignment pegs are included in the design.
