ART phantoms are molded of tissue-equivalent material; they are designed within highly sophisticated technological constraints and follow ICRU-44 standards. They are also designed for accuracy and ease of use.

Features and Benefits

• Anatomy
  • The ART phantom is transected-horizontally into 2.5 cm thick slices.
  • Each slice has holes which are plugged with bone-equivalent, soft-tissue-equivalent or lung tissue equivalent pins which can be replaced by TLD holder pins.
  • Soft-tissue-equivalent coatings produce slices with glass smooth interfaces.
  • These coatings are cut away over the air spaces of the oronasal pharynges, trachea and stem bronchi.
  • Dosimetry holes are drilled in grids 3cm x 3cm or 1.5cm x 1.5cm in 5 and 7 mm diameters.
  • The Male ART Phantom represents a 175 cm (5 ft. 9 in.) tall, 73.5 kg (162 lb.) male.
• Materials
  • Soft Tissues
    • There are unlimited, small variations in density and absorption throughout the human body.
    • Phantom soft tissue is closely controlled to have the average density of these tissues.
  • Skeletons
    • RSD skeletons are highly-detailed polymer moldings which reproduce the shape, mass density and attenuation coefficients of cortical bone and spongiosa.
    • They allow continuous production of phantoms, instead of the sporadic production required by the limited availability, variable size and uncertain chemical composition of human skeletons.
    • These problems, plus loss of marrows in dried natural skeletons, make RSD skeletons superior to “real bone”.
    • Molds for the RSD cortical bone and spongiosa were made from human skeletons consistent with the sizes of the soft tissue molds.
    • RSD skeletons conform closely to the standards established by the International Commission on Radiation Units and Measurements (ICRU Report No. 44); mass density is reduced slightly to take into account a small decrease in calcium content for older patients.
• Assembly
  • ART phantom slices are held between aluminum plates by nylon tie rods.
  • Knobs at the end of the rods clamp the slices tightly in proper alignment.
  • The external assembly facilitates film dosimetry, while the internal assembly is used generally with TLDs or ionchamber dosimetry.
